Hi, I have my designed carrier board and an Xavier NX module (board ID 3668 , version 200, sku 0001, revision H.0).
On my carrier board, we have a external eMMC which goes through SDMMC pins (229/227/219/221/223/225).
We plan to flash :
1. bootloader to on-board eMMC.
2. rootfs to external eMMC.
by using one command such as ‘./flash.sh my-board-def mmcblkXpX’.
My question is:
- How can I know if TBoot can recognize this external eMMC ? Any tool can I use ?
- Could you please tell what interface that on-board eMMC and on-board SD card use ?
Which one is used for SDMMC pins (229/227/219/221/223/225) in MB1/TBoot?
How can I enable SDMMC pins for earlier booting program such as MB1/TBoot/Cboot?
Or if there is any guide line , please help to provide it.
