Question
STM32 SPI Bootloader start up application failed.
Hello Together,
Currently, I met an issue about the internal bootloader download application by SPI.
Firstly, let me describe the background.
- MCU, STM32F750V8 rev, Z
- Taget, I want to use the internal SPI bootloader to download the application from the SPI master Side to RAM 0x20004000 and then run it in RAM.
- I follow the document AN4286 which introduced the protocol for the SPI.
- I confirm every step I transfer firmware to slave side and got the ACK, I also run go command (0x20004004)successfully, also got the ACK from bootloader. But the result is not what I want(I make the led flash in the firmware but it doesn't flash)
The above is my processes about how to use bootloader get the firmware, follow I write how the firmware generate.
- I use CubeMX and CubeIDE generate the firmware and there is not any changes in it.
- I could download the firmware by CubeIDE and confirm the LED could flash.
- but when I use the bootloader download the binary and use the Go command to switch the address but nothing happen.
Is there any body know where I am wrong, whether I could not use the binary which generate by the default conjuration settings?
The binary code is very simple that I only write the LED flash in while(1).
The attachment is the binary which download to STM32.
