I am working on LS2085a based custom board. I have two booting interfaces IFC NOR flash which is same as used in QDS board and other is QSPI based serial NOR flash. I am able to boot the board successfully from NOR flash. Now i want to boot my board from QSPI flash. I want to know minimum rcw configuration changes required to boot LS2085a from QSPI flash.
I did the following changes in the existing(working) RCW which was used in IFC NOR flash in order to boot from QSPI flash.
1) changed RCW src = serial NOR
2) BOOT_LOC = Serial NOR
3) FLASH_MODE = Serial NOR (QSPI) 1 channel 24-bit Addressing
4) IFC_GRP_A_BASE = Serial NOR (QuadSPI) enabled
5) Also changed PBI data of BOOTLOCPTRL and BOOTLOCPTRH registers to point address of u-boot image. In our case u-boot image is flashed to offset 0x10000.
Are my configurations correct or any other specific changes are required ?
