I had debugging problems with a H7 target, and by stepping thru the boot process I found the following line in SystemInit(): /* * Disable the FMC bank1 (enabled after reset). * This, prevents CPU speculation access on this bank which blocks the...

After Upgrading to Cube 1.13.0 with CubeMX6.9.0, my project is no longer compatible with CubeMX 6.8.1.When I start the CodeGenerator, it creates a file \Drivers\CMSIS\Device\ST\STM32H7xx\Source\Templates\system_stm32h7xx.cwhich is a duplicate for the...

I'm still struggling with the ethernet code. I have some custom hardware that where several H743 controllers are powered on at the same time and sometimes they don't get all a connection (no IP address from dhcp). But I can reproduce this error as we...

I have a project with STM32H743ZI, lwIP, noOS. I've read the document with the suggested settings for MPU, linker file, lwIP head placement and applied the changes to CubeMX generated code.Additionally, I have set the MEM_ALIGNMENT to 32 bytes and ad...

I'm using VSCode/Debug-Cortex with STLink V3Mini. The target is a board with STM32H743VI and SWD. The board has only basic swd with GND, 3V3, SWDIO, SWCLK. There is no reset line, unfortunately also not on other headers.When I start debugging, the de...

Thanks, of corse it as a minor issue as it should have no affect. But it would be clearer if it is conditionally inserted.

old subject, but I ran into the same trouble, so just for my records:On a H7, Set_Config() is public, but changing BaudRate and OverSampling did not work. I found that a __HAL_UART_DISABLE() before and __HAL_UART_ENABLE() made it working.But in the I...

After upgrading from 1.12 to 1.13, the debugger stops suddenly after hitting a breakpoint. Also stops after a few steps. The debugger console does not show exceptions.edit:I've reverted now also to 1.12.1, 1.13.0 is unusable for me. The debugger stop...

I haven't designed the hardware and I know this document. I'm pretty sure that the oscillator is not a problem. It is about the SMA communication with the MDIO/MCLK and about 2 MHz clock. This communication fails when the phy is not yet ready. The da...

Yes, the PHY has its own crystal.I have measured the time from power up until LAN8742_init, it is only 3 ms. So the H743 ist simply too fast...The PHY chip needs more time for reading the strapping bits (also 23 ms?) and seems not to respond within t...
