Hi, Working on SAML21 based project it came to my attention also the presence of an 8Kb additional flash that is called "Read-While-Write" (or RWWEE in the datasheet) that, as far as I understood, can be programmed and read in a very similar way to the normal flash. This is currently not supported anyhow in RIOT as far as I see. This is also present in other SAM chips (a grep on the RIOT sam0 common includes tells me saml21, samd21 and samr30).
Well it's just 8Kb (in saml21 case) but a customer is asking about it ;) Before starting to fiddle with code I was wondering if any of you already saw this or had intention to work on or had problems with this or.... any information would be great :) On the other side I would also be interested in an opinion if the access to this facility should eventually be kept totally separate from the current (with some possible code redundancy, but with the possibility no to include it into a project) or could be integrated into the current flashpage driver (bringing some complication of the logic of the current code) Thanks!
