STM32H743ZI SDRAM. RAS/CAS pins not working
I checked for signals. all signals ok except PF11 / PG15 pins (RAS/CAS). Pins configured same as others dram-related: AF12, alternate function (gpio registers checked).I check this signals in GPIO mode, pins and pcb traces working well. But in altern...
Resolved! What is the difference between STM32F446RET6 and STM32F446RET7?
Is there any documentation on the differences? Are these two part numbers functionally identical?
guidance needed to debug hard fault
My code, which is in progress, stopped working with a hard fault. This is on a STM32G431 with several timers running and two dma channels. I can single step through the code with breakpoints on the timer IRQ's and the DMA IRQ's and it works for sever...
