AM62L: eMMC boot only once

Tony Tang

Part Number: AM62L

Tool/software:

After flash to eMMC, can only boot once, customer add log in SPL, find it change eMMC boot partition configuration. so can't boot on second power cycle

change to boot up from SD card, modify boot partition, switch back to eMMC boot, can boot up one more time.

=> mmc partconf 0 1 2 1
=> mmc bootbus 0 2 0 0

same result with booting from Boot partition or UDA, Is it intend to do in this way?

Tony,

For AM62L :

texasinstruments.github.io/.../UG-Memory-K3.html

The recommended method is to flash and boot eMMC with MMCSD boot from UDA in fs mode.

Hi Praneeth,

#1. That is two different aspect issue, why UBOOT change eMMC boot parameter which result in can only boot once? this is SW issue, not a silicon issue.

#2. I tried eMMC FS mode according to the procedure to fdisk UDA to two partition, mkfs mmc0blk1 to fat format, copy tiboot3.bin, tispl.bin u-boot.img from sd card to mmc0blk1, reboot to UBOOT to set:

3.1.1.3.1.6.4.3. Boot from UDA

=> mmc partconf 0 1 7 1
=> mmc bootbus 0 2 0 0

Set boot mode to [0:15] : 11000011 0000 0000 , power up can only boot up with below log, the log is same as DFU boot with default tiboot3.bin. Does it need patch to support eMMC UDA FS boot?

Please provide detail steps to boot from eMMC FS.

#3. Is the sector name wrong? MMCSD should be eMMC? if yes, hope it be corrected right there, no need to wait next release, and leave the error there forever.

1/. The issue was logged as K3ROM-8417
2/. I'm attaching a uboot log booting from eMMC UDA/FS with Linux SDK 11.0.5.2 on AM62L EVM for your reference, where BOOTMODE[15:0]=0043 to select eMMC UDA/FS.
Best,
