Not working on the latest Arch Linux (Python 3.12)? #24

Closed RadxaYuntian closed 2 months ago

RadxaYuntian commented 2 months ago

Just cloned the repo and tried boot-g12.py:

Serial showed G12A:BL:0253b8:61aa2d;FEAT:E0F83180:2000;POC:F;RCY:0;EMMC:0;READ:0;CHK:1F;READ:0;CHK:1F;READ:0;CHK:1F;SD?:20000;USB:8; so nothing was getting to the device.

First, I reduced the block size for the failed function call back to the default 64 bytes:

         print("Running at 0x%x..." % loadAddr)

It went a bit further:

There is also some output in the device serial:

I tried to play with block size (AMLC_AMLS_BLOCK_LENGTH, AMLC_MAX_TRANSFERT_LENGTH, and AMLC_MAX_BLOCK_LENGTH) for the above error to no avail. There is also another error that I'm getting:

So it is mostly dev.getBootAMLC and dev.writeAMLCData throwing errors on me now.

I'd like to check if this is my own system issue, or if this is an Arch issue.

Can you precise on which usb controller model you are running? Can you run lsusb -vv ?

RadxaYuntian commented 2 months ago

Upgraded the system today and the issue disappeared. The kernel was upgraded from 6.8.8 to 6.8.9 so maybe something was not right in the previous release.
