I own a proprietary design based on STM32H743ZGT6.Two boards were assembled.Initially both boards work identically.After about two days of software bring-up activity on one board following issues were encountered:1) Debug through JTAG is not possible...

For Channel=5 and Rank=1 the result is ADC_SQR1=0xA (incorrect).Should be 0x140.

Dear Kaouthar,Thank you for your support.The issue was on my side.Of course, I modified the structure element (in main.c) by hand and did not realize that the Rank=1 corresponds to:sConfig.Rank = ADC_REGULAR_RANK_1;but not:sConfig.Rank = 1;Best regar...

I performed the same steps - i.e.Generate the code with LL using STM32CubeIDE 1.12.0.Debug project and execute the code step by step.Check the ADC_SQR1 register value in the SFRs.and see that ADC_SQR1=0xA .Still not clear how:((Channel & ADC_CHANNEL_...

Hello Kaouthar,You wrote:> I made some tests with Nucleo-H723ZGHow exactly you obtained the ADC_SQR1=0x140?What is the MODIFY_REG formulae in the LL_ADC_REG_SetSequencerRanks() in your test project?Thank you,Fedor

Hello Kaouthar,Thank you for the reply.I'm using the STM32CubeIDE Version: 1.12.0 and STM32Cube_FW_H7_V1.11.0.The board is a proprietary one based on the STM32H743ZGT6.The issue can be observed on any evaluation board.Possible software example is "Lw...
