libncurses5 and libtinfo5 were replaced by libncurses6 and libtinfo6 in Ubuntu 23.10.No Debug possible anymore inside IDE.Update not yet available.Is it safe to replace version 11.3 of the toolchain with i.e. 13.2?Will it work to overwrite the plugin...

1.) HAL_Delay(x) hangs forever when restarting CM4 using Hardware Timer for Systick. Every unit was forced with RESET/RELEASE. Any firmware change could not solve it. Have to repower the board. Happens in Normal and Engineering mode!2.) HAL_Init() ha...

Hello.I cannot use Ethernet with my 2 weeks old NUCLEO-F767ZI (chip version Z).Probably the LAN8742A does not work properly anymore.After initilization I perform a check: if (HAL_ETH_ReadPHYRegister(&heth, PHY_BSR, &regvalue)==HAL_OK) { if (regvalu...

My SysClock is 200 MHz, AHB Prescaler=1.I want to slow down some timer to filter glitches from external input.But when APB2 peripheral clock is set lower than 50 MHzthe Ethernet DMA does not send any data: no ARP, UDP or TCP.Even when ABP2 timer cloc...

Open STM32CubeProgrammer and connect via ST-Link.Click on "OB" for Option bytes.Open tab "User configuration" and look for "BCM4" and "BCM7".In your case you want BCM4 to be checked as well as BCM7.Click Apply and Disconnect.

Unfortunately this issue still exists.I use TIM17 for Systick. I start the CM4 fimware, stop it and start it again.It hangs at HAL_Delay(5).My code lines before HAL_Init():TIM_HandleTypeDef htim17;htim17.Instance = TIM17;HAL_TIM_Base_Stop_IT(&htim17)...

SOLVED. I forgot to initialize with VIRT_UART_Init(&huart0);

But there are still no #defines in main.h or anywherebut now there is code generation for GPIO.I tried with and without RESMGR_UTILITY.

It's so annoying! Equipment: Power supply 6A, native Ubuntu 22.04, USB Highspeed 480MBit/sUSB port disappears everytime and do you know what?The board also, because I put it in the trash.Tried many times to build a different linux image.The only thin...
