I manage to build RB5 HLOS image using code from Chipcode and Code Aurora. I built in the qti-distro-rb-perf mode. Then I follow the release note and use fastboot to flash the images onto the board using the following command:

#adb reboot bootloader

#fastboot flash abl_a abl.elf

#fastboot flash abl_b abl.elf

#fastboot flash persist persist.img

#fastboot flash system_a system.img

#fastboot flash system_b system.img

#fastboot flash userdata userdata.img

#fastboot flash boot_a boot.img

#fastboot flash boot_b boot.img

#fastboot reboot

But after I flash the device, the device can no longer boot anymore. Any idea what could be happening? Do I need to flash the CDT as well?

Hi Da.teng,

Boot issues  might be related to CDT being erased/corrupted.
We saw this while switching back and forth between different builds (Linaro <--> LE <--> LU). 

Re-flashing the CDT resolved the issue for me, can you please try to re-flash the CDT? 

Best Regards,

Rajan.

Hi Rajan, 

Thanks for the information! I didn't manually flash the CDT myself. What I did was I flashed the LE build that came with the SDK-manager 2.1.0. After that, I flashed the image I built myself from LE source and the device is now able to boot again.
