Hi!
I'm trying to transfer a Lua program from my computer to an STM32F4 Discovery. The shell is working fine with minicom and I am following these steps 1. Input recv in the shell. It outputs Waiting for file ... CC[...] outputting C's and making me hurry. 2. Open minicom's dialog for sending files, select the program file and hit Enter. It says: Retry 0: Got 72 for sector ACK Retry 0: NAK on sector Retry 0: Got 72 for sector ACK Retry 0: NAK on sector Retry 0: Got 72 for sector ACK Retry 0: NAK on sector [...] Retry 0: Retry Count Exceeded Transfer incomplete I have tried options like -a, -b, -X for sx, but to no avail. I disabled flow control. I have tried screen. I have tried cutecom. All to no avail. How is this done properly? I'd especially like to hear of ways to avoid those minicom dialogs. -- Just a command in a separate shell that sends the file after I have sent "recv" to eLua.

Dear Richard, > 2. Open minicom's dialog for sending files, select the program file and > hit Enter. It says: [...] > Transfer incomplete The XMODEM protocol supported by eLua uses 128-byte packets (the default, original XMODEM protocol). In your case, if minicom (it probably uses -1k by default?) doesn't support this with sx, your transfer will fail. > I have tried options like -a, -b, -X for sx, but to no avail.

Can someone please suggest a program for using XMODEM on GNU/Linux? Best, Raman Links: [1]: http://www.ayera.com/teraterm/ |
I've had success using: sx -bl 32 config.lua Best of Luck On Wed, Aug 7, 2013 at 12:13 AM, raman <[hidden email]> wrote:

(My fault, probably, but I don't know what I'm doing wrong.) I have even experimented with TeraTerm on wine, but that's worse. Next I'll be trying TeraTerm on a Windows machine and then, possibly, write my own program for sending. Or is there a better way still?

Or is there a better way still? It also depends on the elua end, since there are several flavours of XMODEM protocol. While working on our 120KB flash image, where there is no space for the shell, I wrote an xmodem receiver in Lua that works the same way as the build-in shell one. It's small, so implements the barest subset of XMODEM. In my tests (with minicom on Linux as the host end) it transferred data faster than the built-in elua xmodem written in C, probably due to better luck with protocol timing windows. You could give it a try and see if it and your Windows box like each other better. Usage is to put it in "recv.lua" on the embedded board (on SD card or in the ROMFS), then say require "recv" to the Lua prompt. You can they use it the same as the "recv" builtin, to store the data in a file or to put it in RAM and run it directly. https://github.com/martinwguy/elua-tools Enjoy :) < _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |
