Wrong elf file download.

[giwonKIM]

Hello, I use cube programmer.

The chip I use is STM32H743ZGT6, but I accidentally downloaded the elf file of STM32H735VGT6.

So I tried to download it again, but the st-link itself won't connect. How can I fix this?

Strap BOOT0 HIGH, cycle power twice, attempt connect, and mass erase part

Can I use stlink when entering boot mode or should I use uart?

The SWD/JTAG will work as normal, but MCU just not running your broken code, as thus likely allowing for connectivity or side stepping LDO vs SMPS settings
