DB820c boot problems

Products Support DragonBoard 820c
#1

Hi,

I have a db820c that I’m having a hard time bringing up. So I thought I should go through the recovery process. I flashed a recovery image, but when I boot I get the following:

I’ve tried all of the sdcard images here: Linaro Snapshots
but I get the same result

I tried doing the USB recovery outlined here:

But the command:

sudo <PATH to qdl>/qdl prog_ufs_firehose_8996_ddr.elf rawprogram.xml patch.xml

won’t execute because there is no rawprogram.xml, only rawprogram[0-5]

At one point I was able to get into fastboot, but I can’t any longer. Now what I get is:

Is there something obvious that I’m doing incorrectly?

#2

Could you please try the following (while board configured in EDL mode):

sudo <PATH to qdl>/ prog_ufs_firehose_8996_ddr.elf rawprogram*.xml patch*.xml
#3

hmm, I seem to have borked something. In EDL mode it should show up as a fastboot devices, correct? I don’t see anything on the serial console when in EDL mode and not fastboot devices show up.

I set the switch as per the documentation for EDL mode:

Set switch S1 to ON,OFF,OFF,ON

I ran the command, it executes and quits almost immediately without any error.

#4

AFAIR, in EDL mode it should show up as a serial device (either ttyUSBx or ttyACMx). Check your system log when you boot in edl.

#5

You are correct, it shows up as /dev/ttyUSB1/ for me.

But then when I run qdl it disconnects:

And I don’t get any response

#6

Similar issue here. I am using USB flashing tool.

In EDL mode, on power up I get:
[16751.368862] qcserial ttyUSB0: Qualcomm USB modem converter now disconnected from ttyUSB0
[16751.368895] qcserial 3-2:1.0: device disconnected

[18011.011070] qcserial 3-2:1.0: Qualcomm USB modem converter detected
[18011.011292] usb 3-2: Qualcomm USB modem converter now attached to ttyUSB0

But if I run qdl command:
[18382.622710] qcserial ttyUSB0: Qualcomm USB modem converter now disconnected from ttyUSB0
[18382.622732] qcserial 3-2:1.0: device disconnected

what is the proper procedure?
