你好
对于定制电路板、我们 希望 让您可以从内置 EMMC 存储器 SDINBDG4-8G-XI2.我将使用 Yocto 来构建映像。 电路板不能从自定义引导分区引导。 仅当在硬件引导分区上刷写 tispl.bin 和 tiboot3.bin 时才会引导。 首先、我将介绍我到目前为止努力使工作正常的步骤:
1. Under the Linux (booted via TFTP) I flashed our custom image to eMMC memory:
tiboot3.bin, tispl.bin, u-boot.img and uEnv.txt are on the first partition (64M)
2.在 U-Boot shell 中,我将软件分区配置为可引导:
mmc partconf 0 1 7 1
mmc bootbus 0 2 0 0
3. After switch to boot from eMMC (on board switch) and reboot nothing happens. But when bootloaders are flashed on mmcblk0boot0/1 partitions, the board starts.
What step is missing?
Thanks
