Hi,
usually, all the HW related adaptations are done using Device Tree update. Strongly not recommended to change code for simple pin muxing change.

Accessing board UART is a must to go further. STLINK might also help later.
At least, using the starter package binaries from EV1 board will not work as you have only a 16-bit DDR.
Maybe the starter package of DK1 board might be more closer to your...
Hi @asadullah4571
this might be due to some security on the phone or the board date/time not aligned (as there is no RTC battery on the board).
Regards.
By console, I mean the UART output as they could be very useful indication (even if messages are not always clear as FSBL size is constrained to put many debug strings).
FSBL could fail initializing the STPMIC1 (using I2C), the DDR, etc...
As your ar...
Hi,
not sure to understand the meaning of adding an LDO. Converting buck4 3.3V to 1.2V is more expensive than simply connecting VDDCPU/VDDCORE to BUCK1 as listed in AN5587 and does not bring any gain (as Overdrive still not possible).
