Hi,

Have hit an issue trying to program the STR750F daughter board, the 1st few times I have managed to program and debug my program all was OK.

I have been messing around with the PLL in my startup code and tried to reprogram but then it came up with the error "Error during connection to target".

I have tried going into the debug advanced options and erasing the flash but gets the same error. If I try to check the connection to the target again the same error.

I have rechecked the hardware using the STR711F, STR730F and SRT912F boards I have and they all work OK and run with the debugger and Rlink.

Is this an issue with the clock and the JTAG as I had this issue with my STR711 boards and the workaround was to hold down the reset and erase the flash ?

The mother board is V2.10
The serial number of the daughter board is RAIS070115-2
Software is BN747-ST7-ARM-80C51-P1-STR750

Any help appreciated

Regards Mark
