Jason, Flash API V210 is not applicable for C2000 devices. For F2837xD, Flash API V1.54 should be used. Flash API V1.54 reference guide link: www.ti.com/.../spnu629 Useful wiki page for Flash API and ECC usage: processors.wiki.ti.com/.../C2000_Flash_FAQ C2000Ware has Flash API usage example at C2000Ware _x_xx_xx_xx \device_support\f2837xd\examples\dual\flash_programming Please use V1.54 Flash API and see if that helps. In the above wiki page, please search for "If the Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector, xx) does not wait for the erase operation completion, how do we know whether the erase operation succeeded or not?". Can you check the value of FMSTAT you get from Fapi_getFSMStatus() and see if it indicates any failure? Thanks and regards, Vamsi
