[U-Boot-Users] CFG_MEMTEST_START board configuration setting
Hi guys. Here is an easy one.
I have a question about a certain configuration setting (two of them to be precise) in board configuration file (include/configs) .
CFG_MEMTEST_START, CFG_MEMTEST_END - usually are set to only part of the memory range. Is this because the test is time-consuming? What are the guidelines for selecting this range?
Thanks.

No. But you probably don't want to overwrite the exception vector code (or U-Boot will crash in the next timer interrupt) or the area where U-Boot has it's code, stack or heap (or U-Boot will crash immediately).
the guidelines for selecting this range?
The simple rule is: don't crash the system.
