Hello,
As soon as i check-mark TFTP in Net_Config.c, my main program stops executing, even one line of code!
Oh i've included TFTP_uif.c into my project. All compiles fine and burns to LPC 2129 on MCB2100, but even the led routine at the start of main() does not execute.
Any suggestions?
Thanks and regards,
Akshat
Too much data? Does the stack still fit in available RAM? Have you taken a look at the map file?
Please check your TFTP_Demo example if it compiles and runs.
However have in mind that TFTP needs a file system behind. If you enable the FFS, then you need to provide also a heap of at least 0x800. Othervise the system will hang in pre-main function, trying to execute a semihosting swi. In other words the system is trying to send a message on stderr that the heap size is too small to continue.
And don't forget to uncheck the Use MicroLIB checkbox in Options for Target and use a standard library for FFS aplication. And you also need a correct retarget.c. All that is in the TFTP_Demo example setup correctly.

Modified telnet_demo to use ppp and lpc2129, but no success :(
still the code does not execute main()
sorry not telnet_demo but TFTP_demo! Pardon me...
Did you setup the heap to 0x800 in the startup file?
0x1000
Please take a look at the MCB2140 HTTP_Demo example. It is configured for the serial PPP Server. There is also a LEDSwitch example for MCB2130 which also uses a PPP Server mode.
Take them as a reference and check if you have configured your example properly.
If you run your modified TFTP example. Does it stop in the retarget.c?
Oh franc what i would have done without you! I changed heap to 0x800, i guess 0x1000 was getting too much!
Runs tftp, but can't be too sure as i can't create files on the board. I've yet to figure the RAM configuration for FFS.
Cheers and thanks!!!
Right! It PUTs the file. But then it gets lost, i.e. i can't GET it.
