Hello,
We're working on a custom board for the STM32H750IBX. Our boards arrived. The first time, the chip was installed poorly and shorted out. We assembled a new board at the SMT factory with the new chip, but we still can't connect to the chip to program it.
We checked the voltage and the connection as best we could. We couldn't check the chip itself because it's a BGA package. However, we did an X-ray, and everything looks fine.
We tried connecting with STMCUBE IDE and ST_LINK Utility, but they still can't recognize the target.
We've exhausted all possible solutions and are asking the community for help.
