Hi,I am working on custom board with STM32MP257. I am trying to enable i2c7 but it is RIFSC blocked.When I try to change the rif configuration for i2c7 the flashing process is interrupted and I cannot download the FW.Any help would be appreciated.Tha...
So coincidental enough all the projects I have done before required a RTC /w LSE. I am now working on a project that does not need a LSE, and I am finding that TF-A keeps throwing a panic because of this. The protos we had fortunately had the circuit...
We have designed a product using the MP257, and based the board layout of the EVK and we are now taking the combined product through RED & FCC testing.Generally the board is very quiet, but we are experiencing problems with the Ethernet clocks and we...
I am trying to probe TC358743 (HDMI to CSI ic) to STM32MP257f-dk. The ic is able to take input from the HDMI from my laptop (I is being checked as when i give an edid as input from v4l2 then the screen of my laptop gets extended).The problem is in re...
I have a STM32MP257 custom board and I'm listening on UART6.When I boot, I get nothing. No messages or other text. I have not yet implemented any Linux onto my SD-card.The issue is that I have my USART6 boot pins on PF13 and PF14, instead of PF4 and ...
