❗ Build Failure: BL2_BASE – "invalid suffix 'x' on integer constant"

I’m working on building the img for the LX2162A Clearfog board using the lx2160a_build setup.
https://github.com/SolidRun/lx2160a_build/blob/develop-lsdk-21.08/README.md
I’ve set the TARGET as LX2162A_SOM_CLEARFOG_18_9_0 and am running the build with the correct environment variables.

However, the build fails with the following compiler error:

plat/nxp/common/setup/ls_bl2_el3_setup.c: In function ‘ls_bl2_el3_plat_arch_setup’:
<command-line>: error: invalid suffix "x" on integer constant

I’m building natively on the board (Ubuntu 22.04) using the runme.sh script.

./runme.sh SERDES=LX2162A_CLEARFOG_18_9_0

Any help or insight is appreciated.
Thanks!
