LPC1788 AND SST39VF6401B Download fail.

tian hua

Hello,

I have a project setup for the LPC1788 (uVision 4.22) and SST39VF6401B for some reason I can not figure out I get the following error when I try and download to the flash:

Erase Done.
Programming Done.
Contents missmatch at: 90000000H (Flash=64H Required=1CH) !
Contents missmatch at: 90000001H (Flash=64H Required=DFH) !
. .
. Contents missmatch at: 90000062H (Flash=64H Required=3CH) !
Contents missmatch at: 90000063H (Flash=64H Required=DFH) !

Flash Download failed - "Cortex-M3"

LPC1788 will write and Erase succeed

but sst39vf6401b write and Erase fail.

in the working status sst39vf6401b(0x90000000) can be write and Erase!

why?

Thanks.
