7.3 – Test Flash
Enabling this choice adds the Flash test to be included to the test
sequence. The first block of each Flash device is checksummed, then it’s
read and saved on a disk in the service software. After the block is saved,
the physical block is erased, and then programmed from the file where the
contents was saved.
After programming, the block is checksummed and the result is compared
to the original one. If the checksums are equal with each block, the test is
considered successful. The test is performed with the default parameters
shown below:
Filename default:Flashtest.bin
Start Physical Address default:3A00000h
Start Relative Address default:000000h
End Physical Address default:3A00000h
End Relative Address default:00FFFFh
Start Physical Address default:3C00000h
Start Relative Address default:000000h
End Physical Address default:3C00000h
End Relative Address default:00FFFFh
Start Physical Address default:3E00000h
Start Relative Address default:000000h
End Physical Address default:3E00000h
End Relative Address default:00FFFFh
