Hi,Working with G474, having same configuration as you have, and working with Internal and External Loopback, but not receiving ACK (ErrorCode), when configured in Normal Mode, could you detail changes in hardware or filter part, please.
I have upgraded ST-Link v2.1 to V2J33S7, using STM32CubeProgrammer, and use with a developed board with H743 and works fine with STM32CubeIDE 1.0.2 for debugging. But using NucleoH743ZI2, that already have a STLinkV3, does not work for me, same issue...
