Tool/software:
Hi:
I use the u-boot ti-u-boot-2024.04. SDK version is 10.00.00.08
In below step, I try to flash u-boot image from fastboot tool.
1. I boot into u-boot mode.
2. Set u-boot environment for eMMC partition:
env set fastboot.fastboot_raw_partition_tiboot3 0x0 0x400 mmcpart 0
env set fastboot.fastboot_raw_partition_tispl 0x400 0x1400 mmcpart 0
env set fastboot.fastboot_raw_partition_uboot 0x1400 0x3400 mmcpart 0
env set fastboot.fastboot_raw_partition_env 0x3400 0x3500 mmcpart 0
env set fastboot.fastboot_raw_partition_bakenv 0x3500 0x3600 mmcpart 0
env set fastboot.fastboot_raw_partition_sysfw 0x3600 0x3E00 mmcpart 0
env set fastboot.has-slot:tiboot3 yes
env set fastboot.has-slot:tispl yes
env set fastboot.has-slot:uboot yes
env set fastboot.has-slot:env yes
env set fastboot.has-slot:bakenv yes
env set fastboot.has-slot:sysfw yes
env set fastboot.has-slot:tiboot3
env set fastboot.has-slot:tispl
env set fastboot.has-slot:uboot
env set fastboot.has-slot:env
env set fastboot.has-slot:bakenv
env set fastboot.has-slot:sysfw
env set fastboot.partition-size:tiboot3 80000
env set fastboot.partition-size:tispl 200000
env set fastboot.partition-size:uboot 400000
env set fastboot.partition-size:env 20000
env set fastboot.partition-size:bakenv 20000
env set fastboot.partition-size:sysfw 100000
env set fastboot_raw_partition_tiboot3 0x0 0x400 mmcpart 0
env set fastboot_raw_partition_tispl 0x400 0x1400 mmcpart 0
env set fastboot_raw_partition_uboot 0x1400 0x3400 mmcpart 0
env set fastboot_raw_partition_env 0x3400 0x3500 mmcpart 0
env set fastboot_raw_partition_bakenv 0x3500 0x3600 mmcpart 0
env set fastboot_raw_partition_sysfw 0x3600 0x3E00 mmcpart 0
3. command u-boot cmd: fastboot usb 0
4. In the windowns side, I command to do "fastboot getvar all". Can get the feedback result like below.

5. fastboot flash uboot u-boot.img. I got the fail
