H750 bootloader cannot jump to the firmware.

[Xlio5]

Is there an existing issue for this problem?

• I have searched the existing issues

What part of EdgeTX is the focus of this bug?

Build system

Current Behavior

Referring to the stm32h7s78-dk version, it was ported to the h750, with the main modifications being the change from XSPI Flash to QSPI Flash, and the starting address set to 0x90000000.
After testing the bootloader's jump to the firmware, the firmware did not execute anything.
However, when using Cube MX to generate a program with an offset of 0x90000000, it was able to jump and function properly.
Environment: Chip stm32h750xbh6, Flash w25q256, SDRAM IS42S32400F
code： https://github.com/Xlio5/edgetx/tree/h750_test

Expected Behavior

Using Cube to generate the app, the normal execution at offset 0x90000000 indicates that the bootloader jump is functioning correctly. With the same bootloader, the firmware should execute normally, but it does not.

Since we have a couple of different boards with h750 that can boot successfully, I suspect an issue on your side.
How did you program the external flash?

[Xlio5]

Okay, during the bootloader phase, I used the following function to enable the NOR flash

  stm32_qspi_nor_init();
  stm32_qspi_nor_memory_mapped();

After completing this initialization process, I executed

jumpTo(0x90000000);

download firmware, when reading the content of the flash, the offset appears to be normal.
