I checked all of the KL series data sheets that I could find (from a KL02 with 32kb up to the KL46 with 256kb) and all have 1kb flash sector size. The KL-series reference manual specifies that SIM_SDID[23:20] define the 'Kinetis Series ID' as 0001 for 'KL Series'. The K series manuals don't say that those bits define the series ID but they are set to zeros (0000 for K Series?) for the few K series parts that I've checked. It looks reasonable, then, to check these bits and set 'granularity' to 0 for KL series parts. I don't think any of the KL series include 'FlexMemory' so granularity of nvm is not defined.
Apart from setting the granularity and the multi-byte read workarounds, the only other thing necessary to get flash working on the KL46Z was to force longword programming (set fallback=1 in kinetis_write) as these parts don't support the section write command. ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
