Re: Atari 520 STE Harddrive (ACSI2STM project) not detected at all

I tried one sd card with image of acsi harddrive volume on it, and one with standard fat32 and files.
But, I have been told that even without sdcard, acsi2stm device should blink orange led, but here it doesn't at all.

I have switch 1772 between two atari, one is atari branded one is not.
But it does not change anything.

Waiting my parcel with the resistors to do the pullup stuff.

Thanks a lot for sharing your experience and idea, that's nice.

Latest attempt.
I rebuild the firmware and I did put it in debug mode.
It appears that the device is awaiting acsi bus, I have the following message :

"-> Waiting for the ACSI bus ..."

it seems like the hardware is not talking to acsi2stm.

I'll keep tweaking firmware and looking for an hardware issue.

any idea welcome !

Out of curiosity, did you build this yourself?

I helped somebody last year with an ACSI2STM problem and the BluePill was fake.

Now his didn't work at all, but when testing it appeared to do something from the log perspective, and that was with an STE too.

Have a look here: Fake BluePill

It seems that the fakes do have varying degrees of functionality as mine kind of worked in my BlueSCSI devices.

Worth checking to see if it is a genuine BluePill.
