Hello Rita,
that's a problem, because current MX8QM GA BSP is 4.14.98, which is only compatible with SCU FW 1.2.x, which in turn is only compatible with DDR configuration file v18.
Using v19 or v20 (the two available RPA tools) won't work.
By removing the v18 version, it is not possible to generate a DDR configuration file compatible with the current GA BSP.
Thank you!
Francesco
