ChibiOS Free Embedded RTOS

Try cat /sys/kernel/debug/usb/usbmon/0u and it will show you all the USB packets so you can figure out exactly which transaction is causing the problem. Would suggest you post the final few lines of that output here. If that file doesn't exist check if you have a debugfs mounted. If not use mount -t...

Board done and ordered - should get 3 simple dev boards in the next 3 weeks or so. Also very interested in the STM32L442. I used the F303 a lot at the moment and the L442 is better and pin compatible but also comes in a lot of leadless packages which I prefer so hopefully including the L442 and well...

its port was already in my plans.

Perfect! Let me know if I can help with code or test. I've just designed my dev board for the 462 so will send off to the fab.

Yes - only difference I can see is that the 452 doesn't have AES but as there's no ChibiOS driver for that anyway, in Chibi terms they are the same as far as I'm aware......

Hi, Yes, it looks interesting and will be supported as soon we can get our hands on a board. Giovanni What do you need? I was just about to design a quick prototype board for it so can send one to you if that would help? My dev designs don't have a built-in st-link though, so you would need a separ...

Any plans to support the STM32L462? Looks interesting as it has crystal-less USB, CAN and AES which are all of interest to me but it's not included in the L4xx hal_lld.h yet.

I could go ahead and add it of course, but no point if Giovanni is going to do it officially soon anyway.....

I know you said your CAN works without filters so apologies for just testing that, but prior to 16.1.7 there is a bug in the baud rate calculations for the 042's CAN in the HAL which causes it to run at half speed so I'm wondering whether it just appears to be working by some luck without filters, b...

Yeah I've changed the code over to the UART driver - it was much easier than I thought, thanks to the good examples in the testhal folders. Thanks Giovanni!

I have an application which needs 9 data bits on the USART. From what I can see, the ChibiOS serial driver cannot be used for this as it explicitly uses 8 bit queues? Could someone confirm I have to use the USART driver if I want to send/receive all 9 bits? if so that's a real pain and would be good...

Hi, I committed fixes in subversion trunk, could you confirm it is working for you before I backport it to 16.1? thanks, Giovanni I use git so my testing isn't 100% conclusive, but I've reverted my patched version which causes the compilation to fail as before, then I've taken your new version of h...
