SC20 Linux Eval Board bricked

Hello,

I Think I’ve bricked my eval board. I’ve create a minimal image from the recipe meta-qti-bsp/recipes-products/images/machine-minimal-image.bb.

After that I’ve do :
$ ls
jimini-minimal-image-msm8909-20201023093707.rootfs.ext4 machine-recovery-image-msm8909-20201023093707.rootfs.ext4 msm8909-boot.img

$ fastboot flash system jimini-minimal-image-msm8909.ext4

$ fastboot reboot

Now my display show me the Tux but the USB port not appear with dmesg or lsusb… The two uart give no feedback too.

What I’ve done wrong? Have you a solution to resolve this problem?

From the UART debug I can have some info, I don’t know how to enable USB or fastboot mode in order to upload a new system.

Hello gilou,

I too got the same error. If your error is resolved, can you share the solution.

Hello The_Martian_Man,

Unfortunately I’ve not fixed this problem. I’ve no answer from Quectel too…

I’ve tried the method given by the document Quectel_SC20_Linux_Packaging%26Download_On_Ubuntu_Guide_V1.2.pdf.

But the board is not responding now… I’ve a timout error. See this other post

Hi gilou,

Thank you for your immediate response.I have a doubt from other topic. Have you tried to update the images through OTA? If yes, Can you share me the procedure for SC20.

Hello gilou,

My issue has been solved. I have installed fastboot and dependencies regarding SC20.

How do you do that? Can you give me your method ?

I first installed the fastboot
sudo apt-get install fastboot
then
install the depencencies from the below document

ftp://tor.kpi.ua/pub/pavlov/Distrib/UnitedHelp/Datasheet/Quectel%20SC20%20-%20Multi-mode%20Smart%20LTE%20Module%20with%20Wi-Fi%20&%20Bluetooth/Quectel_SC20_Android_Compiling_Instructions_V1.0.pdf

If the error is not solved, just try to unplug the usb and connect to other port.

Thank you, I will try this monday. I’m not using Android but yocto linux, but for upload, there is probably a common way.
Thank you

Hi Gilou,

I have the same issue on my SC20, did you find the solution?
