TUSB9261: Issue flashing the device under Linux OS

Part Number: TUSB9261
Other Parts Discussed in Thread: TUSB9260

Hi everyone,

I'm trying to flash a TUSB9261, used in a custom board, to be able to have a bridge between SATA SSD and an USB of the SBC. We are using a NOR FLASH "GD25D05CTIGR" from "GigaDevice Semiconductor (HK) Limited"; the environment in which we are trying to flash is: Linux Ubuntu 12.04.

Following the flashing procedure ("TUSB926x_Linux_EEPROM_Burner_User_Manual.pdf") we are able to see the device with `lsusb` ("TUSB9260 Boot Loader"), so we can compile the flashburner and launch it. The procedure continue without any error ( only sometimes the message "hid_set_output_report failed with return code 8" appears) and at the end of the procedure we can see the message "PROGRAMMING SUCCEEDED!!!!".

Anyway, after we populate the jumper (J13 on the DEMO BOARD) and power cycle the part, with `lsusb` we see again "TUSB9260 Boot Loader", as if the memory was not written at all.

Thank you for your suggestions,

Tommaso

Hi Tommaso,

Just to confirm do you repopulate the jumper before executing the write operation? The jumper should only be removed at initial connection to allow the boot-loader to be detected by the OS.

Hi Malik,

Yes I confirm I repopulate the jumper J13 before executing the write operation.

Best,

Tommaso

Hi Tommaso,

Sorry for the delay here. as I have mentioned we do not have much support for linux. As best I can tell it seems the hid reports used to tell TUSB9261 what to write to the Flash are not being sent to the right deivce (i.e device is not open). Are there any other log messages that might be useful here?

Hi Malik,

Another log message is "ERROR: HIDIOCGREPORTINFO failed"; this only appears sometimes.

I'm trying to change the FLASH memory and try to reprogram, i'll inform you if something change.

thank you for your support,

Tommaso

Hi Tommaso,

Did changing the flash work for you? The additional error message did not add any additional context.
