Hi, Denk: During debug u-boot with JTAG tools, maybe turning off optimizations was recommended.

Dear TigerLiu@viatech.com.cn,
In message FE7ADED5C2218B4786C09CD97DC4C49F9403F2@exchbj02.viatech.com.bj you wrote:
I tried to turn off gcc optimazition by changing config.mk file: OPTFLAGS= -O0 #-fomit-frame-pointer
But failed to compile u-boot, it tipped:
Don't do it, then.
Q: why would you want to switch off optimization? That's almost always a bad idea...
Best regards,
Wolfgang Denk
