ST-Link Error With Riverdi Display And STM32H757XIH6
I have this Riverdi board with a STM32H757XIH6 microcontroller. I have been using it consistently and loading touchgfx programs on it. Today I was trying to use the 40 pin header and program one of the gpio pins on it to act as a gpio output. I put an led on a ground and the PA4 pin, which was the pin I was using on the 40 pin header, to verify the toggling code was working. Nothing happened and so I tried to load a basic program onto the board using stmcubeMX and selecting the STM32H757XIH6 microcontroller. I selected the PA4 pin on the .ioc file and generated the code. However, when trying to run the program I get this error,
.
Not sure if it was that program or touching the multi meter to certain pins that cause a hard fault or something. I would not think a multi meter could do anything like that, but I'm trying to figure out why all of a sudden I am unable to upload a program to the board when I have been consistently.
I also tried to reset the mc with the stmcubeprogrammer, but I can not connect to it. The programmer recognizes the st-link is connected
But when I try to connect to it, I get this error.
I have tried to hold the reset button and plug in the st link to trigger dfu mode. I was able to upload a new firmware, but that did not do anything either. I tried a software and a hardware reset. Please help.
