Tool/software:

AM2434 ALV Package

SysConfig 1.21.2+3837

mcu_plus_sdk_am243x_10_01_00_32

I'm trying to add a QSPI flash device, but there is no option to change the OSPI driver from 8 to 4 data lanes even when I select 4S-4D-4D mode.

I read elsewhere in the forum that I should import the flash configuration .json to resolve this.

However this gives me an error.

Before clicking the "LOAD FROM JSON" button:

After clicking the LOAD FROM JSON button:

The flash name changes to "ERROR RUNNING SCRIPT" but there's no further information given.

I have tried loading both:

mcu_plus_sdk_am243x_10_01_00_32\source\sysconfig\board\.meta\flash\S25HL512T.json

and the attached .json file that I generated using the ospi_flash_diag_am243x-lp_r5fss0-0_nortos_ti-arm-clang project.

Steps to reproduce:

1. Create new sysconfig file and add a Flash device.

2. Press "LOAD FROM JSON" and select one of the referenced .json files.

The .json now loads thanks.

However sysconfig still has 8 data lines selected for this QSPI flash and there is no option to change that as far as I can see.

There are checkboxes for each Signal. I believe you may uncheck whichever ones you do not require.
