Espruino on STM32L496RGT6 for a new board

Hello to all
I would like to know if it is possible to port on this micro:
STM32L496RGTx with 1Mb of flash and 320Kb of RAM, uSD, USB, two 2 resonators for RTC and USB and other features.
Do you think it will be difficult to do the porting?
For the USB resonator do you recommend 12 or 24Mhz?
Thanks

Hi - there's already a port to the STM32L496G Discovery Board at http://www.espruino.com/STM32L496GDISCOVERY so I imagine it would be pretty easy to get it working on what you have planned.

In terms of the high speed oscillator, just use whatever ST did in the above board as it'll make your life a lot easier

Hi Gordon
Thanks, concering STM32L496DISCOVERY does not have a high speed oscillator for USB but I think that 12 or 24 MHZ should be enough, just play with PLL.
I start from scratch, a tip from where to start to do the pin mapping and to start?
I mean to build the porting for STM32L496RGx
Thanks

Hi Robin
I'm finishing the board. Maybe as soon as I finish it I will publish it and someone can help me with the remap :)
Thanks
