iW-Rainbow - G15D Custom Board using NXP BSP LF6.12.20_2.0.0 boot problem

Hello NXP tech

I am using a Custom Board base from iW-Rainbow - G15D board.

iWave board info:
https://www.iwavejapan.co.jp/product/imx6Q%20Q7%20development%20board.html

I don't have any source code from iWave.
I try to use NXP BSP LF6.12.20_2.0.0, and customize uboot-imx based on mx6sabresd.
I try to boot from sdcard with my modified uboot.imx.
This how I tried:
1, change BOOT_CFG1 to 0000 0010, BOOT_CFG2/3/4 to 0000 0000.
2, change usdhc controller, ddr calibration setting and uart debug port.
and nothing comes up.

3, try to toggle a GPIO in board_early_init_f(), also nothing in oscilloscope.

the attachment is how I modify uboot.

Dear NXP tech, Please help to find where is the problem, or what I missed?

HI @wenyan,

Thank you for contacting NXP Support!

Unfortunately, we don’t have documentation to support bringing up your board, as we do not provide software for it.

Based on the manuals I’ve reviewed, iWave should be able to provide the necessary patches for your board, or you may use their official sources directly.

Best regards,
Chavira
