at_modem_signalling.c fRspAnalyze_CGMR() line 1583. In L4 the compiler is v5, on U5 the compiler is v6. It seems the main issue is that the device_info pointer is not initialized before this code executes. CS_get_device_info() is called later after C...

Thanks for the links and fast reply. I have been testing out multiple configurations using CubeMX and was not able to come up with one that would cover both requirements; individually was not an issue. I will review the linked material more deeply to...

Hi Imen,There was no error message; the touchscreen just didn't work when using the binary from ST's site: STM32CubeU5_Demo_STM32U575I-EV.hex. The touchscreen worked out of the box, but then after downloading the binary image it did not. I tried that...

Thanks jiangfan, but running the demo from source in the debugger (both Keil and STMCubeIDE) does enable general touchscreen interaction.

Hi Walid,Thanks for the reply. Unfortunately, I’ve already moved on with a different approach using osThreadFlagsSet/Wait and don’t have the time to recreate the previous iteration. In the future, I will save the code in the troubled state for refere...

X-CUBE-CELLULAR on B-U585-IOT02A Hard faults when executing AT+CGMR handler. The SID_CTXT.device_info pointer is NULL when memcpy is called to copy the response into the struct. On L4, the pointer is NULL also but the code continues.

Is there a way to use the output of one timer as clock source for another AND reset on GPIO edge trigger?
