Thanks.
I tried using the sdphost to load flashloader firmware to RAM:
>sdphost.exe -u 0x1fc9,0x0145 -V -- write-file 0x20205800 ".\ivt_flashloader.bin"
>sdphost.exe -u 0x1fc9,0x0145 -V -- jump-address 0x20205800
Then blhost to configure NOR flash:
>blhost.exe -u 0x15a2,0x0073 -- fill-memory 0x2000 4 0xC0000007
>blhost.exe -u 0x15a2,0x0073 -- configure-memory 9 0x2000
Does the "configure-memory 9" operation from RAM flashloader firmware above configure the NOR flash to Quad mode (ISSI external Flash IS45S16160J) and this needs to happen ONLY one-time during manufacturing if the same operation is used (set Quad Enable SerialNorQuadMode_StatusReg1_Bit6)? Thanks.
and blhost to perform the following
