RadioOperator,

I found your documentation about the stlink v4 mini very interesting. But instead of writing my own bootloader I used the micropython bootloader. This way one can advance swiftly. I provide a link, in case you could use the source in your project. Could you give me your opinion?

Howdy!

Thanks for this great posting, much to learn here...

As a first step I caught just one error on compile with Keil 5.25.2.0:

.\Listings\STM32F723_YAB.axf: Error: L6218E: Undefined symbol LL_RCC_GetUSARTClockFreq (referred from usart_stm32f7xx.o)

Am I missing an include, or something simple? (compiler is set at c99)

Thanks

Awesome project!

I'm building a utility which implements the ST USB DFU protocol and encryption, it can already flash YAB without issues. But when I flash YAB (@0x08020000) + slv3app1.bin (@0x08040000) it does not jump to the app and remains in YAB mode. I've also tried flashing slv3app1.bin directly to 0x08020000 over USB and it does work likely because the target IROM settings.

I cannot compile the project myself without a license though to resolve the issue. Would you be able to compile the The CMSIS apps to run at 0x08020000 and push them here?

Hello,

PA7 is the SWD direction signal. High mean SWD write.

Please consider to add to the pinout.

Bye

Hello,

thank you for the STLINK-V3 pin description at
https://github.com/RadioOperator/CMSIS-DAP_for_STLINK-V3MINI/blob/master/STLINK-V3MINI/Sch/STLINK-V3MINI_GPIOs.JPG
However for the 32pin edge connector Pin 7 I see a missmatch. UM2502 labels it as "Bridge SPI CLK" while the JPG says "PB5/PC7". However neither of PB5/PC7 has the SPI2_SCK functionality. Maybe it is even connected to a third pin or something is wrong.

Bye

Please describe how to reflash the Mini!

Hey @RadioOperator ,

In the past there were attempts to gather the STLink V2's firmware via downloading a dumper code through the official bootloader:
https://lujji.github.io/blog/reverse-engineering-stlink-firmware/
https://lujji.github.io/blog/reverse-engineering-stlink-firmware-part2/

It might be useful to check whether it is possible with the V3 because using the factory bootloader for downloading custom code would be a great possibility I think. I do not have device at hand at the moment, but I will look after the possibilities later. I just opened this issue to give you a heads up.

Hello @RadioOperator

May I ask you to upload the source of this image in any textual format:

Many thanks in advance!

希望能够加入已经编译好的固件以此来快速测试
