[microblaze-uclinux] not able to transfer files using ftp

[anand_12 <anand_12@xxxxxxxxxxxx>]

Hi all

 After assigning an IP address to my microblaze-uclinux board(memec spartan 2E),I am trying to write the kernel image onto FLASH using a tool called flashw available in the uClinux-dist...i wanted to transfer the image from the host machine to the board using FTP(with a client compiled in)
..i am able to establish a connection with the host and execute some standard ftp commands..but when i try to do a file transfer..i get the following messages...

FYI,i have mounted the ext2 file system on /var and /usr...

here is the session detail :

...hangs after this.....

meanwhile in XMD,I g(a/i)ve these commands

XMD% mbconnect mdm
..................
XMD% dow -data ........ 0x80000000
XMD% con 0x80000000
PC reset to 0x80000000,Clearing MSR interrupt enable bit
Processor started.Type "stop" to stop processor

---------------------COMMENT-----------------------------
..the kernel boots as usual here..as seen on the hyperterm..
and then i start the ftp session with a remote host on the LAN..i get that above message when i attempt a file transfer ..i am not able to recv(hv not tried send())files from the remote host(ascii/binary)...it hangs after
this..
-----------------------------------------------------------
RUNNING>stop
ERROR<Stop> ::Unable to Stop MicroBlaze
Microblaze Pipeline Stalled execution Instruction at >>PC:0X81F36FF8,
MSR:0X00000002
RUNNING>

 as shown above after the hyperterm hangs..i execute the above command in the XMD window...and I get this error msg..

Can anyone tell me what do those "munmap.." messages mean?

Moreover why does 'stop' not work..How to debug in such cases?

TIA

cheers
