STM32L462 Looks Interesting

Postby avrhack » Sun Jul 09, 2017 5:12 am

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.....

Hi,

Yes, it looks interesting and will be supported as soon we can get our hands on a board.

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 separate programmer or loop across from another Nucleo board........

If that's of interest PM me details of where to send; I'll get it designed today and sent off for PCBs. Usually takes about 3-4 weeks for them to come through plus a little time to build and post on to you.

Hi,

Let me check my usual ST sources first.

I have a nucleo L452RE. Is it a similar chip?

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......

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.

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 as L462 in Chibi is an easy ask.

I've now got the dev boards back from the fab and built one. Any progress on the port? Can I help in any way? Would you like me to send you one of the dev boards built up?
