[U-Boot-Users] U-Boot/Kermit Problem
I am facing a problem in loading a binary file from minicom. Whenver I try to load, it is going in an infinite loop.
=> loadb 100000 ## Ready for binary (kermit) download to 0x00100000 at 9600 bps...
I configured kermit as told in the DULG/SystemSetup Manual.... Only change I made is
set speed 9600 instead of 115200
I am getting stuck here. After going through the u-boot source code .... The calling sequence is ....
-load_serial_bin -k_recv
Inside k_recv the code where I stucked up here is ...
----------------------------ACTUAL CODE----------------------------------- /* get a packet */ /* wait for the starting character or ^C */ for (;;) { switch (serial_getc ()) { case START_CHAR: /* start packet */ goto START; case ETX_CHAR: /* ^C waiting for packet*/ return (0); default: ; } } ----------------------------ACTUAL CODE UP TO HERE------------------------
I think it continiously in the for loop. When I press control-C then it will come comeout saying ....
## Total Size = 0x00000000 = 0 Bytes ## Start Addr = 0x00100000
Can anyabody help me why it is happening ? Any help will be appreciated.
-regards, -Ashish

Hi Ashish, Check whether your serial_getc() function is returning 0. Your serial_get() function should not return 0 if LSR_DR is 0. I hope this will solve your problem.

The DULG also warns you NOT to use minicom - for good reasons.
If you use kermit for file download anyway, just use it as terminal program, too.
