Flash write failed when connecting to STM32H753IIK
Hello OpenSTM32 Community,
I faced a problem that I could not connect to STM32H753IIK via ST-LINK/v2 (or ST-LINK/v2-1 on Nucleo-H743ZI). OpenSTM32 version is v2.7.
Even the same configuration successfully connects to STM32H743ZIT6 on Nucleo-H743ZI, but failed for STM32H753IIK. The target is wired by Nucleo onboard ST-LINK/v2-1 as described on STM document UM1974 (section 6.3.4 Using ST-LINK/V2-1 to program and debug an external STM32 application). NRST pin is also connected.
I saw the following error on the console. I confirmed that OpenSTM32 v2.7 for Mac OS and Windows both failed similarly.

By the way, by the same wiring, ST-LINK Utility can flash without any problem.
FYI, when connecting to STM32H743ZIT6 on Nucleo-H743ZI, I saw
