Re: [OpenOCD-user] Trouble programming flash memory on ATSAMD21 chip with STLink V2 interface

Paul,

if we had an "adapter quirk" bitfield and a driver was able to get a 
trustworthy information
"halfword access is emulated" then I go along.

But if the driver tests for a hla adapter, does it mean emulated 
halfword access?

Or do you recommend just to use word write on any adapter? High half is 
marked as reserved,
it should be ok (I checked just 3 manuals of at least 10).
