I'm trying to create a custom QSPI flash loader in IAR Embedded Workbench 9.2 for an STM32H7 microcontroller. I'm referring to the following existing loader:

C:\Program Files\IAR Systems\Embedded Workbench 9.2\arm\src\flashloader\ST\FlashSTM32H7xx_QSPI

However, I need to configure the correct QSPI pins (e.g., clock, IO lines, chip select) for my hardware. Normally, these configurations are available in the .ioc file when working with STM32CubeMX, but I'm not sure how to integrate this information into the IAR flash loader.

My Questions:

1. Where can I find the pin configuration (e.g., .ioc file or other resources) for the default IAR QSPI flash loader?
2. If I need to create my own pin configuration, how should I update the loader code? Are there specific macros or registers I should modify?
3. Is there a recommended workflow for generating a QSPI flash loader using both STM32CubeMX and IAR?

---

My Environment:

• MCU: STM32H745
• Toolchain: IAR Embedded Workbench 9.2
• Flash Device: MT25QL512A (QSPI)

Any guidance or resources to properly configure the QSPI pins and integrate them into the IAR flash loader would be greatly appreciated. Thank you in advance!

This is like the third post on the same topic. For IAR support go to IAR. Or read their related documentation or examples.

Seem to recall the .flash is a .ELF with initialization function to configure the pins.

Expect you're going to need to initialize in basic HAL level code, and the Cube tools are not going to auto-gen the code for you.

Check MSP code generated for your app or your BSP level code. Or Driver BSP type code examples for the DISCO or EVAL boards.

You're going to need to ask IAR what their logs mean!

Hello @Harsh_Gajjalwar 

1. Where can I find the pin configuration (e.g., .ioc file or other resources) for the default IAR QSPI flash loader?
   - The pinout configuration is done within the .mac file.
2. If I need to create my own pin configuration, how should I update the loader code? Are there specific macros or registers I should modify?
   - You should verify the system clock configuration, pin configuration, and memory command if using different memory, as well as the QSPI configuration. These are the basic checks that need to be done.
3. Is there a recommended workflow for generating a QSPI flash loader using both STM32CubeMX and IAR?
   - Currently, there is no recommended workflow from our side for generating a QSPI flash loader using both STM32CubeMX and IAR. This was only done for the H7RS series on our side. You may want to check with IAR to see if they provide a workflow for this process.
