Other Parts Discussed in Thread: AM62P5
Tool/software:
SoC: AM62P5
SDK: Linux 10.0
Boot mode: SPL from eMMC
Reference URL: https://dev.ti.com/tirex/explore/node?node=A__AXEeWNLEW2jak3KzsCN3BA__AM62P-ACADEMY__fp5YxRM__LATEST
Dear Technical Supporter,
While we are able to successfully boot the SPL from the SD card, switching to booting it from eMMC has failed. We have done:
1. Changed to root=/dev/mmcblk0p2, in the k3-am62p5-sk.dts
2. Changed to mmcdev=0 and bootpart=0:2 in the am62px.env
3. Configured boot switches to eMMC mode
4. Copied boot binaries to mmcblk0boot0; copied rootfs to mmcblk0p1.
After reboot, system log shows

Question:
Is it possible that we overlooked some areas that require modification?
Thank you very much.
