hello,
硬件:AM62X-SKEVM开发板
在使用eMMC UDA FS模式启动时(FAT32文件系统),基于MBR格式分区(ms dos)可以正常从ROM boot引导到tiboot3(R5F spl),但是使用GPT格式分区却不能正常引导到tiboot3(串口无任何启动日志)。
据我了解的信息,在FAT32文件系统模式下GPT需要配置EFI实现(UEFI)启动,请问AM62X(/AM623X)的ROM boot是否支持UEFI启动模式?有可供参考的链接吗(UEFI配置问题)?
请看下面e2e工程师的回复。
when booting from eMMC, the ROM on AM62x only supports UDA (raw or filesystem) mode, or boot from the eMMC boot partitions. UEFI boot is not supported. I will need to pass this questions on to our software team to see if UEFI is supported in the bootloader.
抱歉回复晚了,请看下面e2e工程师的回复。
When BOOTMODE pins is configured for booting from eMMC UDA/FS, ROM driver support reading "tiboot3.bin" from MBR format FS, but not GPT(UEFI) format FS.
