Hi Francois
By default, stm32f746-disco is configured in SPL mode, that's what explain you don't get any output in the console
To come back in non SPL mode, you can use the attached patch.

Hi,
I am trying to run the master on a STM32F746 Discovery board [1] by using stm32f746-disco_defconfig. It was built with gcc-arm-none-eabi-5_4-2016q3 [2] and flashed with OpenOCD [3]. A USB-serial adapter is connected to USART6_RX and USART6_TX (pins D0 and D1 of the Arduino connector) and configured for 115200 8N1. No output coming out through the serial interface. It is unlikely to be a hardware issue as output is coming out normally this way when using the U-Boot repository from Emcraft.
I do not know what I am doing wrong, can you help me out?
Cheers, Francois
