Original question:

TUSB9261-Q1: Programming TUSB9261 Using Linux

TUSB9261-Q1: Linux Program Failing to Erase Flash

Part Number: TUSB9261-Q1

Hello,

I was provided with TI's Linux flashburner and FW images for TUSB926x. I am able to write to the flash (PID turns to 9261, SW HB LED is blinking after programming). However, if I attempt to erase the flash after programming, the PID stays as 9261 (rather than reverting to 926b) and the SW HB LED stays blinking. The erase command runs without any errors; I get messages that the reprogramming has been enabled, and that the flash has been posioned. However, "poisoning" the flash doesn't seem to actually be erasing it.

Is this an issue anyone else has run into? 

Thanks,

Anika

    I just resolved this issue. Used TI's vendor-specific SCSI commands rather than HID commands to erase flash, since its been previously burned with FW. Is the SCSI command library provided by TI? I did not see it used in the TI-provided source code...
