Hi all,
My code base is GLSDK 7.04.00.03 and use J6 EVM.
As I know J6 and J6Eco should pin to pin compatible, so I want to configure GLSDK to J6Eco and run on J6 EVM.
My steps are as below.
1. Already modified u-boot to set it as DRA722_ES1_0. It works when loads MLO and u-boot.
2. But stuck when loading dtb... Below is what I modified and boot log.
ti-glsdk_dra7xx-evm_7_04_00_03/board-support/u-boot/arch/arm/include/asm/omap_common.h
#define DRA722_ES1_0_A 0x07220100
static inline u32 omap_revision(void)
{
extern u32 *const omap_si_rev;
return DRA722_ES1_0_A;//*omap_si_rev;
}
Console log:

My questions are:
1. Supposed J6 and J6 Eco pin to pin compatible entirely. Is there anything still need to careful? Simple understanding, J6 has 2 DDR controllers and J6Eco remains to 1. The PMIC is also different.
2. Which portions of DTS need to change more when runs on J6 EVM using J6Eco setting?
Thanks in advance.
