flash programmer
ZXNet echo conference «hardware.zx»
Hello, All
This device is the result of my struggle with flash ;). I tried to do the best I could
simpler: only mega8515, max232 and socket (with zero effort) are used.
I didn’t draw the diagram - see the description. To communicate with the PC uses a protocol
wake, it all started from this source. If there is interest, I will post the sources.
For now you can sew flash, read UV and sew iic (24Cxx). There are plans to support AVR.

Hello skyther
All serial ones can be sewn from the COM port using 3 resistors
Hello ASDT
it's a pity that it's not for spec
Hello, The Exploited
2 ASDT; Done; for flash drives, and iic turned out to be a free add-on.
The> it’s a pity that it’s not for spec
Or you can do it for the spec: 19200 8N1, CTS/RTS is not used, quite
will pull.
Hello skyther
Why MAX? :) A couple of transistors is enough...
Hello skyther
sky> Apparently you'll have to draw
Where should we run? :)
Armored train towards you: the COM port can actually be connected to the ATS via
resistors, there is no overload on the MK. How about this?
By the way, what kind of flushes are they - 28, 29?
Hello skyther
We are waiting for the full datasheet, so as not to guess “what did I collect?” :)
In addition, just in case, I’ll upload a diagram for pairing the ATS and COM port
(standard adapter for flashing AVR in Algorithm Builder)

Hello skyther
Useful thing. TXD - RXD is hung on PD0 - PD1?
Can you tell me a little more about the MAX connection?
Hello ASDT
Apparently I'll have to draw ;) MAX is connected according to a standard diagram, ZX-multicard diagram
for example you can look.
Hello, ewgeny7
Yes, it’s easy, it’s just that my breadboard has a max and a connector from the motherboard.
Hello, ewgeny7
I posted the diagram in the first post.
Hello skyther
Thanks for the diagram, some nuances were clarified. I'm collecting. :)
Hello, ewgeny7
A little about management:
1. the program has a 64 kb buffer - file->open/save works with this buffer.
Note: open loads the file from the CURRENT address to the end of the buffer (did for more
convenient gluing of roms). Sews only into a zero jar (A16-A18=0), therefore
QUESTION: what is the best way to make the switch?
2. read/write work quite slowly - 64 kb is sewn in 2 minutes :( (no
quartz for fine tuning usart - baud rate 19200)
Hello skyther
sky> QUESTION: what is the best way to switch?
Put "radio buttons" in the menu - 0-64, 64-128, etc. Sampling of senior addresses
Judging by your diagram, they are included in the MK.
Hello skyther
"Maiden not found", even if you kill yourself...
Firmware and program - 0.6, 11.0592 quartz.
What fus table?
“Reset” (turned on) the guard dog and CKOPT. Doesn't help...
Hello, Mikka_A
Mik> no problem.... :v2_wink2;
Mik>;
Mik> today I’ll test everything again and tear it apart
Mik> maybe I’ll come up with some other news....
Good intentions are welcome :)
For the developer:
I use Algorithm Builder 4.7 to develop “my own”.
More than a year.
Excellent IDE, built-in debugger and programmer.
For “other people’s” hexes, I use ByteBlasterNV from Altera with AVReal.
When “stuffing” a clean hex, we have errors in verification (from 4 to 1394).
By deleting the first lines in the hex (with numbers 2хххх) we get “clean” flashing
no errors, but the request does not work. I made a mistake on the MAX232, but it seems that it’s not the problem.
To weed out possible troubles (this applies to all firmware for MK AVR),
I propose to give (like Kamil) a fuz map.
I still haven't started the programmer. There are changes in the circuit - instead of DIP40
I use PLCC44, 32pin connector instead of ZIF. Open the source, Bill! :)
Hello, ewgeny7
ewg> I still haven't started the programmer.
I launched it yesterday.
More precisely, I upgraded the Atmega to a new weight...
Oh crookedness....
Maybe, of course, my hands are crooked or something...
but it's just a bummer.
the only thing it does correctly is write FF - that is, it erases in Russian.
and then... horror dreams... :v2_jawdr;
In general; Andrey, I don’t know what’s wrong, but today I’ll clean it up
experiment, try to return to version 1 with 8 MHz.
Hello skyther
sky> Yes, he really doesn’t sew episode 27. But I have one scheme...
As far as I know, the 27th series is not a bald patch, but an OTP EPROM - One time programming
Electronic Program ROM, i.e. sewn once and for all with great tension
(12-25V)
Hello, Mikka_A
Mik> You know correctly, but not quite.
Mik> there are two modifications of them - otp, and uv - ultraviolet erasure.
Practically these are the same crystals in different cases.
For example:
AM27C512-150PC - in a plastic case, one-time programmable;
AM27C512-70DC - ceramic case with window, UV erasable.
They are programmed in the same way, at Epp = 12.75+-0.25 V.
The price of the first one in Promelektronika = 26 rubles, the second one there = 51 rubles.
Winbond releases electrically erasable crystals with markings
W27C512-45 in a plastic case.
Programming requires Vpp = 12+-0.25 V.
To erase, a voltage Vpe = 14+-0.25 V is applied.
Cost in Promelektronika = 35 rubles.
Hello Romanich
Rom> As far as I know, the 27th series is not a bald patch, but an OTP EPROM - One time
Rom> programming Electronic Program ROM, i.e. sewn once and for all
Rom> high voltages (12-25V)
You know right, but not quite.
There are two modifications of them - otp, and uv - ultraviolet erasure.
but they are sewn, as you correctly noted, with 12 volts for both.
otp from a range of cheap disposable ones (cost less than a buck).
Hello, Mikka_A
You'll have to add 12V to make the identification normal...
Hello skyther
sky> You will have to add 12V for normal identification
sky> do...
I forgot to mention.... gee.. it was episode 29 for me, not 27.... :v2_blush;
I; in general about the difference between programming AT29Сххх (from Atmel) and AM29Fххх (from
amd)
Hello caro
car> Practically these are the same crystals in different cases.
car> For example:
car> AM27C512-150PC
car> AM27C512-70DC
car>
car> W27C512-45 .
and you, let’s say, can answer something offhand about the difference in the algorithm
programming?
for example, in the flasher, which is the topic of the branch, they don’t want to install amd chips.
I came across this yesterday.
and it’s tricky - if you sew FF it’s easy, but the code is crap!
plug on the first cell other than FF.
Atmel is sewn, Vinbond is sewn...
I haven’t found others yet for experimentation....
Hello skyther
sky> You will have to add 12V for normal identification
sky> do...
By the way, what’s going on with your A18 - I’m talking about 29s040....
Hello, Mikka_A
Mik> I forgot to mention.... gee.. I had episode 29, not 27....
Mik> :v2_blush;
Mik>;
Mik> I’m generally talking about the difference between programming AT29Сххх (from Atmel) from
Mik> AM29Fххх (from amd)
IMHO AMD is better - it has about 1,000,000 erases/writes, compared to Atmel
only 1000-10000
Hello, ewgeny7
I went through version 0.6, the glitches seem to have decreased ;) With a decrease in speed
the likelihood of recording increases :)
Hello skyther
sky> I went through version 0.6, the glitches seem to have decreased ;) Downgraded
sky> speed, the probability of recording increases :)
Tomorrow you will get the results....=))
(added)
so where does it lie?
Hello skyther
another...
made support for AMD, but for now in the form of a separate firmware ;)
and now erasing the chip is “normal”
Hello skyther
sky> next...
sky> made support for AMD, but for now in the form of a separate firmware ;)
sky> and now erasing the chip is “normal”
people!
Well, test it!
test!!!!!
and that I am the only one suffering.
maybe we will defeat the bugs in a crowd!!! :v2_clapp:
Hello, Mikka_A
Please tell me if it is possible to flash bios flash drives with this programmer,
for example winbond W49F002U (update the BIOS, that is)?
And what is the best way to sew mega?
Hello rx3l2
49 he doesn’t sew, and doesn’t plan to. only 28/29. why? because the bios can be on
sew it for mom herself.
regarding the mega: there are many different circuits, if you want a normal programmer
assemble, it is better to STK200. for example here:
www.ln.com.ua/~real/avreal/description.html
for greater visuality, use pony (STK also supports): www.LancOS.com
Hello skyther
People, is there a datasheet for this flash drive: MX (logo) 28F1000PPC-12C4?

Hello skyther
Here, I’m meditating on a megabyte of FLASH memory with an organization of 128 kb x 8 bits
quantity 8 pieces.
Flash drives have been recovered from those that were written off and sold for precious metals (there is such a fun thing
in V/Ch, hand over equipment for precious metals) computer boards P1.
Here's what I'm wondering - how these flash drives can be attached to the Spectrum via ZX-BUS in
as a kind of “long-term memory block”?
Chips: SST 29EE010 - 5 pcs. INTEL P29F001 - 1 pc. Winbond W29EE011-15 - 1
pcs. INTEL(?) AT29C010A - 1 pc.
IHMO all 8 microcircuits can be “sewn” with both 12 V and 5 V. The access time is sufficient
not much.
Of course, the resource of rewrite cycles is not particularly large and therefore full-fledged
data drive
there cannot be microcircuits, but they contain the most necessary “service” programs
fitting
in a volume of 1 MB they may well “live” there, so to speak, “for permanent residence”. :)
If anyone has any ideas on how to standardize this matter and at what addresses
in the form of self-made
flash modules by ports, etc. then speak up.
The connection connection seems to be quite simple. I saw this one once
used to connect static RAM chips to the ancient
homemade computer "UT-88".
I'll scan the diagram and post it here. :)
Hello, Orionsoft
2 Orionsoft; пасиб; :)
Hello, falanger
fal> "UT-88"
:) I remember such a miracle, I even wanted to collect it ;)
for spec there is a ready-made solution from Inozemtsev. Unfortunately I can’t give you a link,
but it is on virtual trdos. look, flash drives are used there, yes
also tyrdos is supported :)
Hello, falanger
What questions do I have? I don't understand your question. I'm specifically interested in
what a scheme!

I'm also interested in this scheme. Has anyone done it? Is it possible if it works?
upgrade to SRam so that you can beat and write to them from Tyrdos. After
shutdown in battery mode. (Some ZX-Windows lay there beautifully
:v2_thumb; );

Any more detailed materials on the issue? According to the software for which it was made and
etc.
Hello, Scorpion(lv)
We're going off topic ;) I suggest you go here:

The disk drive is also interesting.
