Dear Expert
Can anyone please clarify the below points
1. I want to use Octal SPI chip selects XSPI_CS0_B and XSPI_CS1_B directly one to NOR and other to NAND. I do not want to use QSPI emulator. Is it Ok?
2. What is the use of the signals CFG_DRV,CFG_SVR0,CFG_SVR1 and CFG_ENG_USE0 in Flex-SPI section?
Why these signals are connected to XSPI_CS0_B, XSPI_CS1_B and XSPI_SCK pins.
Thank you in advance

Hi @mkraj,
1. It is okay if you don't want to use the QSPI emulator.
2. The CFG_DRV is to enable CFG_SVR0 & CFG_SVR1 signals of the design.
For CFG_SVR0, please refer to section# 4.8.8.5 of the LS1028ARM.
For CFG_SVR1 & CFG_ENG_USE0, refer to section# 4.8.8.6 of the LS1028ARM. Also, please refer to note# 5 of Table 1 in the LS1028A datasheet which is applicable to these two signals.
