Part Number: AM3354
Other Parts Discussed in Thread: TIDA-01568
Hi AM335x Champ !
Could you please let me know how to get the uboot patch for TIDA-01568.?
A customer would like to design AM335x board without PMIC.
They are seeing the boot failure issue on thier custom board without PMIC.
I'd like to know the code change regarding removing i2c communication with PMIC. The Unhandled fault from external line fetch error is still reproducible in uboot side even without PMIC CONFIG in u-boot.
The bootloader is too old from SDK 2.x. But they're unable to change the baseline due to their internal restriction. He should figure out on top of SDK2.x.
