STM32F7 EVAL Boot mode

Hi,

I am trying to put the STM32F769i_EVAL into system BOOT mode. I can do this successfully with an F429 Eval but not with the F7 Eval. I can see that when I reset it the normal program does not run , indicating that Bot mode has been entered , but it does not respond to the 0x7f (connect ) command.

I've tried with both my own known working software loader and the ST flash loader. I am using UART 1 which is otherwise working. Ive tries various baudrates down to 9600.

I am pulling up the Boot pin JP1 directly to VDD and resetting the board.

Many Thanks

Imtiaz
