Hi there,
I tried to objdump my kernel and found that there are explicit LMAs in =
it, but ICE/CCS2 still can't load it onto the physical address =
0x10200000.
Is there any means to solve this problem? Without ICE, it's hard to =
debug my kernel before it can successful bring up com port driver.

Thanks and regards,
Colin

Nothing is wrong with them.  You need to adjust your linker script to=20
provide explicit LMAs so that the ICE will load them at the physical=20
address, rather than trying to load them at the VMA (virtual address).
