I build the u-boot-2017.11 and u-boot-2021.07 for P2020RDB-PC and get two u-boot.bin file, 542KB for u-boot-2021.07 and 768KB for u-boot-2017.11. There is something different in these two u-boot.bin files.

In u-boot-2017.11 u-boot.bin file, the last part

Please try address 0xfff80000 if you program u-boot with CodeWarrior.

In fact, we suggest you use u-boot (2021.04) provided in LSDK 21.08 release.

I uploaded u-boot source code in the following link.
