We are using STM32L151VCT6A MCU. I have already programmed and worked on the boards, but for 2nd time device is not allowing to read/write the program. And even the pin numb 72 is low at the MCU.
Posted on January 29, 2018 at 07:27We are using STM32L151VCT6A-ND IC in devices; where I observed that in some of the ICs pin PA13 (JTMS-SWDIO) is low and not able to detect the MCU. Could anyone please help me to solve this issue.
Posted on February 05, 2018 at 10:13No, it was not working before. Changed the cable and checked.With the same design we have done almost 150 boards in that nearly 20 boards(MCU) are not working.ST-link works for other boards.
