[SOLVED] Flash an external OCTOSPI Flash with J-Link

Hello,
I want to use Jlink to flash an external FLASH , This FLASH is memory-mapped to an STM32L4 MCU .
Is it possible to do this ? If yes, Please give me the right way.

Thank's.

Hello RBI, you can make your custom Open Flashloader wiki.segger.com/Open_Flashloader Now I'm trying to increase the speed of my flash loader, in this thread forum.segger.com/index.php/Thr…flash-loader-is-too-slow/

Hi,
Thank you for your inquiry.

If I understand you correctly, your Flash is accessible via the CPU.
If this is the case, you can add a flash bank to the devices XML:
wiki.segger.com/Open_Flashload…ending_an_Existing_Device

Best regards,
Fabian
