ACSI 2 SD

[olivierg]

Hello everyone,

I did not find a topic about this project on the forum.
Has anyone used this product?
https://www.eltradec.eu/index.php/en/project-acsi2sd-en

I cannot program a blank IC. I have the impression that it is the program that I program and not the target, after that I can no longer connect to the programmer (kitprog).

Thanks
Olivier

Ps: I found this project similar but simpler and cheaper: https://github.com/retro16/acsi2stm

How much does it differ from satandisk?

I haven't heard about the one on Cypress SoC, but I've seen the one on STM32 - it is a pity, that it was done on the Arduino IDE, as it has no support for DMA.

I'd be interested in one of those acsi2sd; incase you decide to start making them!

I got one of those eltradec ACSI2SD - this one https://www.eltradec.eu/index.php/en/w/7914 to be precise.

It is very easy to solder (just one or two smd resistors). Be aware that some sturdy, thick wire is needed (not in the kit) to attach the ACSI connector (the only thing to do that‘s a bit fiddly).

Performance is very good, it‘s a tad faster (a bit over 1MB/s) than any of my CE‘s. I think that‘s the peek performance the ST DMA can deliver.

The peak performance DMA can deliver is about 1.8MB/s and it is possible to achieve with P. Putnik's ACSI CF interface (yet, it doesn't support autoboot).

I redone the PCB, to have all the components on the same side and used a stencil to solder.

It seemed to me to have less component than ultrasatan. I don't know if it's faster or slower.

I saw a topic on the German forum, but I dare not ask the question in English.

I dont know how reliable the tool is but; with CE I get these results:

I use the same tools, it's just for compar.

But CE (CosmosEx) i many expensive for users who just want a 'hard drive'.
You know me, I'm looking for not too expensive solutions (And again, this week, I recommend a smallymouse, but the person found it expensive (extreme case)), to bring life back to ATARI machines, if it becomes too expensive, the old user stops and the community disappears.

If this project offers slightly lower performance than CE, it is not important if the price is affordable (max 40 euro, assembed with case).

For reply Dog:
I do not know the performance of Satandisk. But having 2 ICs to program is already boring, more work on my side.

To come back to my initial question, I think I understood why I cannot program new PSOCs, the kitprog is limited to PSOCs already with a bootloader, which is not the case with blank ICs. you need another programmer 'miniprog' and do it in JTAG. On the PCB there are 2 types of connections for the 2 types of programmer, it is not for nothing.

I redo the PCB with the JTAG ....

Thanks
