DM385: Starting tftpd on the CSK

John Wicks

Part Number: DM385

We are trying to do development with CCS on the 388 CSK running the IPNC application (RDK 5.2) using RSE from a Ubuntu machine connected via Ethernet to a CSK development board, but we cannot start the tftpd on the target so we can view the file system remotely and transfer executables cross-compiled in Ubuntu to the target for debugging. Apparently this comes bundled in with BusyBox which is part of the distribution, but the instructions from the BusyBox website don't work.

Has anyone gotten this to work? If so, how?

Hi John,

What is the issue you face when you try to run tftpd?
Is tftp enabled in uboot? You can confirm this by typing "help" from uboot console.
If tftp is not enable in uboot, you can do so by setting the macro in includes/.h file of DM385

thanks,

Hi John,

Can you please reconfirm the IPNCRDK version that you are using?
IPNCRDK v5.2 is not yet released , the latest is 5.1 which is for DM36x family.
The supported version of IPNCRDK for DM38x family is 3.9.

Hi John,

If you would like to use a simple tool to transfer a binary in userspace, we have used nc in DM38x CSK

In PC(start first),
# nc -l 1234 < binary_to_send_to_DM38x
e.g.
# nc -l 1234 < uImage

In DM38x CSK
# nc pc_ip_addr 1234 > binary_to_be_received_from_pc(use the same name as the one being sent)
e.g.
# nc 192.168.1.2 1234 > uImage

You are right, I got that wrong. We are actually plan on developing on a 369 and a 385 and have them stream video btwn them wirelessly. We are using 3.9.1 on the latter and would be interesting in getting something similar for the 369 (which would have been 5.2, but which we understand has been cancelled).

Hi John,
You can use IPNCRDK v5.1 or DVSDK for DM369.

While this is helpful, the reason why I specifically want to use tftp is that FTP is integrated with CCS/Eclipse's Remote Systems Environment. So the "real" question is how to get RSE to work with the 388 CSK dev board. While I can invoke a shell to Telnet from CCS to the board. I want to be able to browse the filesystem on the target from CCS and to copy files over easily.

Hi John,

Got it. We also faced issue with tftp not working in CSK. Our requirement was to just transfer a file, which we could achieve with nc. So did not explore further on tftpd. Also you can cross compile the latest tftpd code : sourceforge.net/.../ and check if it is working(can use this binary instead of busybox one).

Hi John,

For starting the tftp daemon in 388 CSK, try running the following command from the terminal..

udpsvd -vE 0.0.0.0 69 tftpd -c <dir>

<dir> - directory, that you want to host on the tftp server, you can also use . (dot)for the current directory.

This will start the tftp server on the board, you can send/receive files to/from the board using a tftp client on our host machine.

I've tried this from linux terminal it is working fine, it should work same in CCS too.

Thanks and regards,

Chidvilas
