+After some research I was able to successfully upgrade after editing the SpiFlash.ini file with the parameters of the 25P10VP chip on my board.
+I added the following:
+<file | SpiFlash.ini>
+=25P10VP
+[25P10VP]
+FlashID = 202011
+ReadID = 9F
+WriteEnable = 06
+WriteStatus = 01
+ChipErase = C7
+ReadData = 03
+ReadStatus = 05
+PageProgram = 02
+ClockRate = 32
+PageSize = 10
+</file>
