Dear ST Community,I am now designing a PCB with the STM32L073RZT6. Could you please advise where the BOOT1 pin is located?Inside the datasheet, the only thing that I found is the statement:Boot modes At startup, BOOT0 pin and nBOOT1 option bit are us...
Dear All,I have designed the scheme of my testing board. The STM32F103VET6 is not easy to buy. What can I do now?Thanks.
Hi Folks,I experienced a weird problem when I tried to use the SDMMC interface on the STM32H755 Nucleo board.I set up a very basic test program. I use the template for the H755 Nucleo in CubeIDE. I set the H7 clock frequency to 480 MHz and the M4 clo...
Folks,Is it possible to ascertain which family member is running at run time? I'm doing a bootloader for an L476 for which there are two variants. The 512k version and 1M version. Is it possible at run time to ascertain which one is running? Either t...
Folks,When you have a dual bank STM32, at run time, is it just one contiguous area of memory. So, for example, if you were running out of the top of bank 1 and the next instruction was in bank 2, would the program seamlessly just jump from running ou...
