I’ve been playing around with the WP76xx on the latest release 17.  
Suddenly the yocto linux has become read-only. I’ve tried to flash different images onto it to fix it but nothing is working.  
I’ve tried swiflash -t wp76xx -r which doesn’t work, and I can’t downgrade to older releases like 12 where -r works perfectly.  
Any advice on how to make it read write again?

Thanks

does this help on resetting userapp partition?
