Anyone had a look at this board? looks impressive... Price is a bit steep tho

Re: Atmel SAM V71 Xplained Ultra evaluation board
SAM V71 devices are members of a family of Automotive Flash microcontrollers based on the high-performance 32-bit ARM Cortex-M7 processor with Floating Point Unit (FPU). These devices operate at up to 300MHz and feature up to 2048 Kbytes of Flash, up to 384 Kbytes
ChibiOS actually supports AT91SAM7x?! Is that includes this chip, then we've got ourselves an automotive grade chip with ChibiOS and probably free GCC compiler. http://www.chibios.org/dokuwiki/doku.php?id=chibios:architecturesAutomotive Grade — AEC-Q100 Grade 2 (-40C / 105C) qualified
Not all the peripheral is supported by the HAL http://www.chibios.org/dokuwiki/doku.php?id=chibios:matrix but still, this is pretty interesting.

No unfortunately the AT91SAM7x is a really old ARM7TDMI based Atmel MCU.russian wrote:SAM V71 devices are members of a family of Automotive Flash microcontrollers based on the high-performance 32-bit ARM Cortex-M7 processor with Floating Point Unit (FPU).

These SAM V71 are very new and based on ARM Cortex M7 core.
Now I did a quick comparison and I am not sure there is much of an advantage over -for example- the STM32F7, apart from the automotive temperature rating of course.
So no advanced timer and no 5V Analog connectivity for instance..
