Hello,I am searching for the input/output impedances for my STM32L476RG microcontroller and I can't find any information in the microcontroller datasheet or else where on the web. Are those values given in any documentation? If not, can they be calcu...
ST marked several Disco boards as NRND (i.e. discontinues them).Some of them are easily replaceable - e.g. the 'F0308 by the 'F0, the 'L100 by the 'L152, the 'F7308 (which btw. is only a few months old) by the probably completely identical (except fo...
I'm trying to flash/debug a B-L072Z-LRWAN Discovery kit from Ubuntu 20.04 using openocd, but its failing to connect:openocd -f interface/stlink-v2-1.cfg -f target/stm32l0.cfgInfo : auto-selecting first available session transport "hla_swd". To overri...
I'm trying to use a STLINK-V3 to run GDB on my STM32, but I'm having issues. I've followed the directions on https://github.com/stlink-org/stlink/blob/develop/doc/tutorial.md, but I'm having issues loading the FW using `st-flash`.$> st-flash write f...
Hi, just bought B-L4S5I-IOT01A discovery kit and I have two questions regarding this.Can I use it to program external STM32L4S5 MCU? If yes, is it by using the unpopulated 4 pin ST-LINK debug -connector? Or by the CN5 tag connector and need to buy th...
In STMCubeIDE 1.5.1When starting a debug session NRST is issues multiple times causing a bit of undefined behavior depending on the target and code.First it resets and has the old program run a bit.Then it loads the new program.Which is lets run a bi...
Dear Sir,I have questions about STM32G474RET6. I have 25 MCUs in my hand. After SMD and power on, I found some abnormal conditions. Then, I swap the MCU (NUCLEO-G474RE and my PCB) and use the same firmware, the MCU can work normally on my PCB.I too...
