i use CubeMX, CubeProgrammer, ST-LinkV3set, and IARi made my own Board, modifiy en.MB1363-H745ZIQ-C01_SchematicST-Link can recognize Device when Boot0 to High and PowerOnReset.when Boot0 to Low and PowerOnReset can not recognize Device.What can i deb...
Hi, with the latest release of ST-Link 4.5.0 i've a problem using 'Automatic Mode'.I click 'Start' button, attach the cable to my board, and the flash is done. I detach the cable, change the board, attach the cable to new board, but nothing is done. ...
I wrote a lib to handle different routine that read/write the flash. Everything works fine.The linker file is customized with some page declarations later use to affect some variables to some flash area.I have done all the debug using the embedded ST...
st link is unable to connect with stm32f103r8 in my circuit board, while programming using keil the nrst pin becomes low when debug is applied and unable to program, but using IAR & ST link utility unable to connect to the microcontroller, board is p...
I'm currently using an STM32L4 on a custom board, trying to implement is a composite USB class that allows CDC and MSC at the same time. I am working with the STM generated classes for CSC and MSC, and have written an intermediate composite interface...
