Re: [riot-devel] Cortex M33 support
FYI, Microchip sent me a SAML10 and a SAML11 (Cortex-M23) Xplained boards so I can port them to RIOT. Yesterday I was able to run tests/leds on SAML10, but it is still too early to share my ugly hacked code. As I saw we can reuse cortexm_common stuff because armv8-M baseline and mainline instructions set are 100% compatible with armv6-M instructions set. But I found out some bits disappeared from some registers like SCB_CCR_STKALIGN bit. I also think it would be great to support brand new ARM MCU out-of-box ! Le mer. 17 oct. 2018 à 19:44, Thomas C.

Hi Juan, thanks for pointing out: I'll try and check with our contacts to NXP.

Re: [riot-devel] Cortex M33 support
A crucial feature about this new arch is the availability of secure vs non-secure execution environment within the same chip. => we need to design how to leverage these 2 environments (simultaneously) with RIOT.

[riot-devel] Cortex M33 support
Hi everyone, Is anybody working / wanting to work on Cortex M33 support? Currently there are no chips available for the general public. AFAICT Nordic and NXP are the only ones with pre-production parts. I'm trying to get samples from both. It would be great if we could have at least some basic support for when the devices reach the market. Also, if somebody has closer contact with either Nordic or NXP, it would be great.
