Hi,
Could you pls provide a bin/hex file for this project to us? We can directly flash the micropython firmware to device. many thanks.
https://github.com/mcauser/MCUDEV_DEVEBOX_H7XX_M/blob/master/README.md says "400MHz". Why not 480 as in the specs?
Hello Mike, I tried building this version, but get a compile-time error:
$ make BOARD=MCUDEV_DEVEBOX_H7XX_M
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

I'm doing this with freshly checked out µPy and this repo, running on latest macOS with arm-none-eabi-gcc toolchain provided by latest PlatformIO. Please let me know if you need more precise information, or if there's something further I can adjust or try. The only aes.c
I can see is "../ports/cc3200/hal/aes.c".

Hi Mike! First of all thank you for you great work on this new board.
This post is not for an issue with the code, but rather a warning about the hardware.
Micropyton connection works like a charm.
I tried to connect an OV2640 camera (like this) to the 24pin connector on the back, but the camera started getting hot and finally burnt...
After reviewing the schematic I noticed that the camera connector pinout is not standard.
I tried to contact the vendor with little results.
Just be careful when you connect!
Any guess about what camera to connect?
hello,
want to compile micropython for this board, and i have this error at the end:
arm-none-eabi-ld: build-MCUDEV_DEVEBOX_H7XX_M/firmware.elf section .eth_buffers' will not fit in region
RAM_D2'
arm-none-eabi-ld: region `RAM_D2' overflowed by 805273600 bytes
if you have an idea?
thanck you
Hi !
Thanks a lot for your job !

This seems to be linked to the mcuboard definition file, but I don't understand anything :)
Do you have any idea to solve this ?
Best regards !
Hi,
I have board H7 blue,
I need test whith CDC usb, my teste with Stm32cubeIDE problem clock setinng for USB.
ENABLE USB DEVICE = error clock set
GPIO test ok
see code:
MX_GPIO_Init();
MX_USB_DEVICE_Init();
while (1)
{
CDC_Transmit_HS( buf, sizeof(buf));
HAL_GPIO_TogglePin(GPIOA , LED_A10_Pin);
HAL_GPIO_TogglePin(GPIOA , LED_A15_Pin);
HAL_Delay(2000);
}
thanks,
Carlos.
I just received the H750 board.
ST-LINK V2 requires to connect RST (reset pin) in order to do reset and start programming automatically.
However the board does not extend RST pin to any header pin.
As this can not be solved with current board, We recommend that developer extends RST to a header pin.
I recommend also to make RST available on SWD header as this is the mostly used scenario.
Second, we can not solve this issue now with soldering a pin because developer did not leave any spare pin on headers!
Hi,
few days ago I got 2 boards for my DIY project.
I don't get any communication with the boards, although they seem to be alive:
What kind of communication with this boards is possible?
Thanks in advance,
Michael
Hi!
Who can explain this?
743VIT has 2M, it is ok, no questions.
750VBT has 128k flash.
How is it possible to program it with 400k+ of code?
Or what am I missing?
I have buy this board for create a project but no communication when I connect usb at pc. But the two k1 k2 led working, the k2 led, the light flashes
