Hi there,
I am working on a product where we use the STM32MP157C for our purposes At the moment we have the UART4 attached to A7. I wanted to move it to M4 so that I can start seeing the serial logs coming out of M4 rather than the A7 which is running Linux. So I loaded the .ioc file onto the STM32CubeIDE 1.16.1. I have attached a screenshot of the current configuration on A7 herewith. I then deselected the A7 and selected M4 as shown in the attachment. Saved the .ioc file, regenrated the code and compiled it. But when I try rebooting the STM32MP157C it seems like few early boot messages comes on the serial but then after few seconds it seems to be rebooting and the same few lines keeps coming. I am not sure what I am doing wrong.
But I have noticed this error message on CubeMxIDE:
When I try to move the UART4 from A7 to M4 and select Asynchronous mode it shows an error in HW flow control which like this: HW Flow Control (RS232) Conflict with SDMMC1: Mode MMC 8 bit Wide Bus or/and ADC1: N9 single-ended
Also, the CCB seems to have turned into brick now and I don't know how to recover it? Any suggestions?
Would anyone be able to throw some lights and possible check points please? Please let me know what else I can provide here for any help.
Many thanks
Regards, Vivek
