ChibiOS Free Embedded RTOS

Thank you avrhack for your source, while I see the difference, I have found the problem. SDU2 is not initiliazed, so this make problem to usb init.

@avrhack have you an example? I tring with branch 2.6.4 but with my dualcdc example I have an error. usb 4-2.1: configuration #1 chosen from 1 choice usb 4-2.1: can't set config #1, error -110 Single CDC is working without problem. The error message is different from my previous thread http://forum....

Hi Dmytro Giovanni help me to resolve a problem with my project Dual USB CDC, with some patches. One patch has changed the usb_lld template and his test archictecture STM32. I replicated it on MIPS-PIC32. Could you submit in your repository? diff --git a/os/hal/platforms/MIPS-PIC32MX/usb_lld.h b/os/...

Hi Giovanni,

thank you so much, now it work very well.
2 shell is ok,
2 write command in both shell in the same instant is ok.
Tomorrow I submit your patch in usb_lld STM32 to Dmytro for MIPS-PIC32, and I post a better code example for Dual CDC,
I hope it is useful to someone.

In my test source code I have sduObjectInit(&SDU1); sduStart(&SDU1, &serUsbCfg); sduObjectInit(&SDU2); sduStart(&SDU2, &serUsbCfg2); On SDU1 there is attached the shell. When I open the serial port with my program (minicom for linux or hyperterminal for windows) I expect a pr...

Hi Giovanni,

thank you for your update. I still have problems with flush data on first serial.
I tried to disable the second serial and all work very well.
Sure with your patch serial usb work in all custom implementations.

I had a similar problem and I wrote this post

I tried to develop a patch, very expiremental. Works but is not perfect. I added a field (Endpoint Data) in SerialUSBDriver, so endpoint data is not static. In my test I create 2 shell one for each serial, with different commands. First serial has problem in receive data, I receveid data only after ...

I give me a first reply alone, I think I need to rewrite ./os/hal/src/serial_usb.c for manage multiple SerialUSBDriver. There are static definition of endpoints.
