I'm using STM32H7S78-DK and STM32CubeIDE v1.17.0. I was try to get Segger RTT working so I switched from ST-Link GDB server to OpenOCD because it has in-built RTT telnet server, but couldn't because OpenOCD didn't find RTT area.I reduced the problem ...

We are doing updates on a project which uses STM32H747 and ST cryptographic library (CMOX) / X-CUBE-CRYPTOLIB. It encrypts and decrypts data using these two functions:cmox_cipher_encrypt(CMOX_AES_CBC_ENC_ALGO, ....cmox_cipher_decrypt(CMOX_AES_CBC_DEC...

Why is there no CRYP (Cryptographics) peripheral enabling/configuration option in project configurator (CubeMX/CubeIDE) for STM32H747 ? I tried v1.15.0 and v1.16.0It does not show up:But it exists in register callback list:And it exists in H7 HAL dri...

Good point, I will soon try other methods also, but it often tends to happen that, if you leave something unfixed, someone else or yourself in the future, will hit the same problem and waste time again. And the issue is not with just RTT, whole OpenO...

Maybe it helps. We had several memory leaks in STemWin related code also and found the root case.We used APPW_GetLockedText to get translation texts by translation ID and then used that text in several places like LISTVIEW_AddColumn, DROPDOWN_AddStri...

Hit the same issue with STM32H573, LAN8742 and NetXDuo. DHCP client did not get IP and did not even send out any packets. The solution / workaround was like @Pavel A. said - periodically check if link is up with this:nx_ip_interface_status_check(&Net...

Hello @STTwo-32 I see... reference manual is the same for H747 and H757 so I naturally expected H747 to have CRYP. My bad.The project is already using X-CUBE-CRYPTOLIB, but it has strange issues and that's why I was thinking about using peripheral di...
