How to redirect UUU to Various SDx Ports i.MX8M(x)

[choppad]

Hello NXP i.MX8MM Community:

As UUU is a tool that NXP has created for i.MX family processors, for burning various media devices (eMMC / SD...), with OS image, uBoot, Kernel, etc..., based upon NXP's EVK, in this example 8MMINILPD4-EVK, the eMMC is on SD3 and the uSD is on SD2.  If a customer builds their board, and has connected their target media sources differently say eMMC on SD1 and uSD on SD3, how can one redirect UUU to look at that specific port for downloading an image via SDP?

Please Advise,

DeWayne

Hi DeWayne

port number is defined by uboot environments: sd_dev, emmc_dev in
imx8mm_evk.h\configs\include - uboot-imx - i.MX U-Boot 

#define CONFIG_MFG_ENV_SETTINGS \
    CONFIG_MFG_ENV_SETTINGS_DEFAULT \
...    "emmc_dev=1\0"\
    "sd_dev=0\0" \

uuu uboot  environments are described in
uboot config requirement · NXPmicro/mfgtools Wiki · GitHub 
Example · NXPmicro/mfgtools Wiki · GitHub 

For uboot customization one can refer to Porting Guide included in  

Linux L4.14.98_2.0.0 Documentation

For procedure to generate flash.bin one can refer to sect.4.5.13 How to build imx-boot image
by using imx-mkimage i.MX_Linux_User's_Guide.pdf.
