Did you solve this?
I am trying to build an old project; I installed the latest GNU ARM Embedded Tools (5.4 2016q3) and upgraded from ChibiOS 2.6.7 to 2.6.8 and without adding --specs=nosys.specs to the compiler options, it fails with the same undefined reference.

Re: Sad to see more restricted commercial use
Hi Giovanni, I am developing a product (IP gateway for agricultural telemetry); I really like ChibiOS; I selected it over FreeRTOS and designed the product using ChibiOS 2.6.7 prior to your commercial licensing. The move to a commercial license is a little bracing, but I understand the need to fund ...

Re: USB Serial blocking
Many thanks Giovanni!
I didn't realize the virtual serial port blocked when not connected, I had assumed it behaved like a standard serial port. I appreciate you confirming this!

USB Serial blocking
I am new to ChibiOS and am using it with lwIP over Ethernet. The code generally works, but for debugging, I added some chsnprintf() statements to display status on the USB serial shell each time I transmit a lwIP packet. I've noticed that if an active USB serial shell connection is not present, the ...

Re: 2.6.7 usb_lld_pump: no return statement
Another approach to disable the bogus warning for GCC is to disable the warning just for the problem function. For example, my usb_lld.c is modified as follows: #if defined __GNUC__ #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wreturn-type" #endif static msg_t usb_lld_pump(...

Re: STM32-E407 Ethernet performance!
Sorry I'm being slow, but I really have looked...I downloaded the latest ChibiOS-master (is this the right place to get it: https://github.com/ChibiOS/ChibiOS), and went through the folders and could not find community. Is it somewhere else? BTW, I am really enjoying ChibiOS; I have only been using ...

Re: STM32-E407 Ethernet performance!
I couldn't find lwip in 3.0.0. The os/ext directory only has CMSIS. Where is it? I tried downloading it separately but the directory structure is very different.

Re: STM32-E407 Ethernet performance!
What lwip are you using to test in 3.0.0?

Re: STM32-E407 can't blink led
I know this is an old post, but I had a similar problem: for a rev E board, you need to change the top level Makefile to use boards/OLIMEX_STM32_E407_REV_D *and also* change the board.mk file in OLIMEX_STM32_E407_REV_D (which still points to the pre-rev-D files).

Re: STM32-E407 Ethernet performance!
I found the problem! The problem is in the board.mk file in boards/OLIMEX_STM32_E407_REV_D. It refers back to the source files in the original OLIMEX_STM32_E407 board directory instead of to the files in the _REV_D directory, so even when you change the reference in the top level Makefile, it is sti...
