qdl: failed to initialize libusb: Permission denied #83

Open rarenicks opened 6 days ago

rarenicks commented 6 days ago

Hi, I am trying to recover my Qualcomm RB5 device using QDL model I am able to see the device in lsusb : Bus 001 Device 004: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

Also set the proper udev rules for the device, still facing the permission issue. "qdl: failed to initialize libusb: Permission denied"

I have given all required permission for the device, but the issue looks not with the device permission but with the qdl not being able to use libusb.

Host system : Description: Ubuntu 22.04.5 LTS Linux helios 6.2.0-39-generic #40~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Thu Nov 16 10:53:04 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Installed qdl using snap "snap install qdl"

Thanks, Avdhesh

Please check https://docs.qualcomm.com/bundle/publicresource/topics/80-70014-253/ubuntu_host.html?vproduct=1601111740013072&versionId=1befb000-28cc-4b51-8b35-81601178edee, in particular the section "Update udev rules
". If that works for you, we should update the README file accordingly.

Hi I was able to run qdl after building it from github source

During flashing "./qdl prog_firehose_ddr.elf rawprogram?.xml patch?.xml"

Got this error :

[PROGRAM] flashed "aop_a" successfully LOG: INFO: Calling handler for program [PROGRAM] flashed "tz_a" successfully LOG: INFO: Calling handler for program [PROGRAM] flashed "hyp_a" successfully Unable to open BTFM.bin...failing

Do you have any idea about this error or point me in the right direction ?

Are you saying that you have a different behavior when you build from source vs when you are using the Ubuntu snap package? Or have you also modified the udev rules, as I pointed out earlier?

During flashing "./qdl prog_firehose_ddr.elf rawprogram?.xml patch?.xml"

Got this error :

the BTFM.bin file is referenced in one the rawprogram XML files, and needs to be 'flashed', but is missing from your local folder.
