Hi Satish,
(gdb) target remote com1
com1: Permission denied.
This was happening becuase you had GDB open the same port locked by
Hyperterminal. On Hyperterminal "Disconnect" before typing ?target remote
com1" on GDB. <I guess someone else also explained the same>. And you can
"Connect" back on Hyperterminal after GDB connection is closed.
RAM: 0x00000000-0x04000000, 0x00004948-0x04000000 available
RedBoot> load -v -m yMODEM
CCCCCCCCC Can't load '<null>': Timed out
Terminal method:
--------------------
Try this ->
load -r -m xmodem -b 0x40000
& select "Transfer" >> "Send File" >> browse to the target file (binary
only, you cannot send elf images like this -- hello.bin) & send the file
with XMODEM. --- Same things can be done from minicom also
If you see the ?C?s go very fast (faster than on C per 3 or 4 seconds) then
you have to fix your delay_us routine.
After download is done, issue this command in Redboot ->
go 0x40040
You may have to use different addresses for load & go.
Cheers,
-Mike.
