[SOLVED] External flash proggramming using GDB server

Hello. I have a board with STM32f746IG controller and S25FL128S qspi NOR-flash memory. I'd like to program my code using GDB server. How to do this? I've never done this before. I also want to use GDB server for debugging. Is it possible with the code located in external flash? Thank you

S25FL128S flash is CFI compatible. Firstly i must to write configuration script for stm32f7 controller in gdbinit file or what? Help please. Maybe somebody has examples for stm32f7 controller and other qspi flash?

Hello Artem,

both GDB Server and programming of CFI flash are described in UM8001, which is part of the Segger J-Link software & documentation pack :

  • Chapter 3 "J-Link software and documentation package" Section 3.3 "J-Link GDB Server"
  • Chapter 6 "Flash download" section 6.5 "Setup for various debuggers (CFI flash)" subsection 6.5.2 "J-Link GDB Server".
Best regards,
Niklas

Hi,

as clarified via e-mail: You are trying to program a QSPI flash which comes with CFI info but not a parallel NOR flash with CFI info (this are two very different types of flash / CFI info).

The native generic (Q)SPI flash programming support for the ST STM32F7 device series has been delayed. Currently, we plan to have support available by the end of this month / during December depending on the daily interrupts.


Best regards

Hello,
Can you tell me when the QSPI flash programming (for stm32F7x6) will be supported by J-FLASH Segger ?

Thanks in advance.

Hi,

For requests in the future, could you please contact us either via e-mail OR via the forum but not via both?
As my colleague already wrote you via e-mail: Planned to be available in approx. 3 weeks.
