Describe the bug

Hello RT-Thread community,

I'm trying to run FinSH shell on my FH8630D board with RT-Thread 2.0.1.
When I boot the RT-Thread binary via U-Boot:

go 0xA0000000

I see the shell prompt:

finsh />

But when I type commands:

ls
help
cd

I get errors like:

Invalid token
Unknown symbol
-1610418204, 0xa002f7e4

My RT-Thread configuration:

#define RT_USING_FINSH
#define FINSH_USING_SYMTAB
#define FINSH_USING_DESCRIPTION
#define FINSH_THREAD_STACK_SIZE (4096 * 2)

Board memory:

DDR start: 0xA0000000
Heap: RT_TICK_PER_SECOND=100
Stack sizes: init thread 10 KB, finsh 8 KB

The kernel was loaded at 0xA0008000, entry point 0xA0008000.
U-Boot version: 2021.04
CPU: ARM1176
Board: FH8630D

I suspect it might be a memory mapping / image type issue.

Has anyone encountered similar behavior with FinSH shell on RT-Thread 2.0.1 on FH8630D?

Thank you.
