Hello sir. Hope you are well.
Excuse me, do you need to activate the MCSPI3 MCSPI4 UART8 UART9 I2C4?
It dosen't need to configure the uboot. uboot is only bootloader.
I'm a AOSP expert.
I have experience in cross-compiling of linux kernel, configuring dts and building to dtb.
Do you need the vm inwhich is compiled the TI SDK? ok. I can do it.
I'll complete your project successfully. Thanks, regards.
