Modify Uboot configuration to add support for NOR flash ( Since DM6446 already has NOR support enable, take example from DM6446 code, then change DM365 board configuration (/include/configs/davinci_dm365_evm.h: Add NOR support)
Hi,
你的bootmode管脚是否已经配置为从Nor启动?
手册上有:
If BTSEL[2:0] = 001 - Asynchronous EMIF boot mode (NOR or OneNAND). This mode is handled by
hardware control and does not involve the ROM. In the case of OneNAND, the user is responsible for
putting any necessary boot code in the OneNAND's boot page. This code shall configure the AEMIF
module for the OneNAND device. After the AEMIF module is configured, booting will continue
immediately after the OneNAND’s boot page with the AEMIF module managing pages thereafter.
