J-Link provides a flash loader for the RA8x1 MCUs suitable for programming code & data into external flash at 0x8000_0000 or 0x9000_0000.

However currently this flash loader will fail to program the external flash if the flash has already been configured into OSPI mode (for example by application code that has previously been programmed into the internal flash).

This can lead to errors being displayed such as:

e2 studio :

J-Link log file :

J-Link commander :

This problem can be avoided by resetting the OSPI flash device into single bit mode before programming. This can be done using the JLinkScript file contained in the attached ZIP file : RA8x1_Reset_OSPI.zip. This uses the OM_Reset (P106) pin - which is expected to be connected from the RA8x1 MCU to the flash device - to trigger a reset of the flash.

If using e2 studio, this JLinkScript can be added to the launch configuration:

If using other tools, see the information on SEGGER's wiki site : https://wiki.segger.com/J-Link_script_files#Using_J-Link_script_files

Alternatively, you can carry out an initialise operation in the RFP (Renesas Flash Programmer) tool to mass erase the MCU, and then do a full power on reset before attempting to program the OSPI flash device.

Enable OSPI Flash on EK-RA8D1 board
3c90689 
Enable the OSPI Flash on the EK-RA8D1 board and move the
const data for img_ebike_bg_large.c to the OSPI flash
using the linker script

need to add the RA8x1_Reset_OSPI.JLinkScript to the
debug configuration->Connection Settings->Script File :-
${workspace_loc:/${ProjName}}/RA8x1_Reset_OSPI.JLinkScript
