Dear all,

I am newcomer of this mailing list. So, I am sorry if following
question is one of FAQs.

I am in trouble for writing an OS image into FLASH ROM from
bootloader. When I try fast command for the bootloader through
minicom, it hangs up as following. Then, the cursor is bringing at
end of last line, that is, next of "115200b". Even if I type
rx command without previous fast command, the bootloader also hangs up
after displayed a line of "C" characters.

Change to 115200b

I tried writing OS image procedure for two uCsimms which I bought
at same time. Then above situation is confirmed for both of them.

Do you have any idea for the above problem?

Yoshikazu
