I have bought a new DragonBoard 845c to run AOSP. And I have successfully flashed the devices and entered fastboot mode following this instruction (https://www.96boards.org/documentation/consumer/dragonboard/dragonboard845c/installation/board-recovery.md.html).
The output is as follows:
cliff@cliff-lab:~/Downloads/dragonboard-845c-bootloader-ufs-aosp-41$ sudo ../qdl/qdl prog_firehose_ddr.elf rawprogram?.xml patch?.xml ... partition 1 is now bootable LOG: INFO: Calling handler for power LOG: INFO: Will issue reset/power off 100 useconds, if this hangs check if watchdog is enabled LOG: INFO: bsp_target_reset() 0 cliff@cliff-lab:/media/cliff/93a85f64-b831-40b6-bbab-2c208df42999$ fastboot devices a2c48e07 fastboot
However, when I try to flash AOSP images, it fails.
cliff@cliff-lab:/media/cliff/93a85f64-b831-40b6-bbab-2c208df42999$ ./device/linaro/dragonboard/installer/db845c/flash-all-aosp.sh android out dir:./device/linaro/dragonboard/installer/db845c/../../../../..//out/target/product/db845c target didn't report max-download-size sending 'partition:0' (44 KB)... FAILED (command write failed (Success)) finished. total time: 0.000s < waiting for any device >
And when I use command “fastboot devices” again, there is no output, which means the host cannot detect any fastboot device.
What should I do now? Thanks.
