Could you please change TQM823L.h:

-#define CFG_FLASH_BANKS_LIST { CFG_FLASH_BASE }
+#define CFG_FLASH_BANKS_LIST { CFG_FLASH_BASE, CFG_FLASH_BASE +
0x400000 }

and try again?

There was a switch-over to use the CFI driver (see git history of file
TQM823L.h). AFAIK the CFI driver needs a list with fix start addresses
of each bank to start the CFI query on.

Best Regards,
Jens
