do you have another solution for us

[Hmizr.1]

We are using stm32H743

We need a frame buffer of 150K to our LCD. we do not have an external RAM, so we use the 412K internal RAM.

We also work with USB (Full speed mode).

each peripheral work on it own , but not together. if we enable both of them they are not working not even if the USB buffers are in another RAM section.

there isn't any compilation or linking error, but nothing is working on the board.

we asked her and you told us to increase the size of heap and stack bu its not help

Going to need to look at how the two projects merge together and the differences between the two. Look specifically at pins and clock sources, and peripheral clock settings.

You're going to have to do some debugging to refine "not working" in to some more specific failure mode.

Have the Hard Fault and Error Handler routines output actionable data, and add instrumentation with diagnostic​ output to understand the flow and behavior encountered internally in real time.
