The STM32F746G-DISCO discovery board (32F746GDISCOVERY) is a complete demonstration and development platform for STMicroelectronics ARM® Cortex®-M7 core-based STM32F746NGH6 microcontroller.

FYI: Few examples currently functional on disco-f746ng

I just received a disco-f746-ng board (sticker shows MB1191 B-04 2155007267) and only one of the examples listed on the mbed page dedicated to this board worked for me.

The examples that don't work: (compiles and downloads, but no LED or LCD action as expected):

DISCO-F746NG_blink_led DISCO-F746NG_LCD_demo DISCO-F746NG_LCDTS_demo

The example that works (i.e. LED blinks and serial port spits out stuff but unable to read ADC reading):

Nucleo_analog_loop

I spent a lot of time trying different versions of ST-link and two versions of the bootloader firmware (one really old - I think it was V2.J21.M5 - and one really new - V2.J27.M15,) I saw some forum posts about a new version coming out within the last year and breaking everything so I wanted to try some older firmware versions but couldn't find any on the interwebz.

Maybe someone that know more of the history of that board can give it a shot and update the examples or something so new users don't struggle too much to get going. Thanks,

Hello Paul!

I have some experience with this board, there are a few more working examples on mbed.org in public repos, u can try Mandelbrot program or various else, even I have released a small keyboard lib for that board. I haven't understood what exact problem u have encountered but I believe with mbed ad STM u should better stick with latest firmaware. And one more advice: original BSP libraries for that board do not compile in current version of mbed, u should backdraw to 121. Feel free to ask anything about it, if u think u have got a problem!

Good luck!

I do have the same problems. The basic Blink or LCD demo for the 476G on mbed do not work. These compile OK and load OK but nothing happen. Any clues? Noticed the problem with the new version BSP and avoided to update.

Deluded, I do not feel mbed is very serious yet, and Keil does not make it with that board if you do not buy the pro version (very very expensive). Programming with the ARM/GCC needs to be very expert on this and need also good nerves to pass the compilation.

Did you try the Touch Screen example?

Hello, It looks like it is fixed now I tried to launch the LCD Demo (https://developer.mbed.org/teams/ST/code/DISCO-F746NG_LCD_demo/?platform=ST-Discovery-F746NG). I have updated every library and the display works normally.

I did the same with https://developer.mbed.org/teams/ST/code/DISCO-F746NG_blink_led/?platform=ST-Discovery-F746NG and it works normally. The led1 that is located near the RESET button is blinking

Mbed library revision is the #130

Kind regards

Hi, You can use STM32CubeMX and free compilers like TrueStudio and others. In Cube , you can find many examples that run everything in your board. Like LCD,SDRAM,QSPI Flash , etc
