Would you not be better off zeroing it?
At least, that is another option
Once you have a bootable pbp, you can again try writing SPI, from os, not rkdeveloptool
--edit--
Sometimes, for flash, it is good practice to write zeros first, then write image
No left-over, not overwritten junk
Especially if new image is smaller
