Re: [U-Boot] Incorrect memtest range on MPC8536DS

Dear Felix Radensky,

Hi,

If run without arguments, mtest hangs on MPC8536DS. I guess this is because of the following definitions:

#define CONFIG_SYS_MEMTEST_START 0x00000000 #define CONFIG_SYS_MEMTEST_END 0x7fffffff

I was able to successfully run mtest on 0x00100000 - 0x10000000.

What is the largest safe range for this platform ?

It depends on RAM size and stack usage. Usually 1 or 2 MB below stack base is safe enough.
