Other Parts Discussed in Thread: AM69
Tool/software:
Hi Expert,
Customers can execute 0167.mksdboot.sh on the machine
and follow the documentation below
software-dl.ti.com/.../How_to_flash_emmc_device.html
No error messages appear during the process, but still cannot be started using emmc
Customers also found several problems
1. If the SD card is not inserted, not only will the computer fail to boot, but there will be no message from the debug port (not a single character).
2. If you start the computer without inserting the SD card, although it will stop, if you insert the SD card after a few seconds, you can start the computer again, there will be messages, and you can enter the OS.
3. Insert the SD card to boot, enter uboot, and specify emmc to boot. It will still boot from the SD card.
Refer to the following file operations
software-dl.ti.com/.../UG-Memory.html
and enter the following command
=> setenv mmcdev 0
=> setenv bootpart 0
=>boot
4. Insert the SD card to boot. After entering uboot, pull out the SD card and then specify emmc to boot. It will stop at the position where the SD card is read.
The log of this debug port is as attached (AM69 boot log.txt)
Is it possible to boot from emmc without inserting the SD card?
Thanks
Daniel
