Solution:
GSRD 2.0 \u2013 How to enable GSRD to boot from Macronix flash
GSRD 2.0 deliverables is target to CertusPro-NX Versa Board with Winbond flash.
Please follow below steps to modify default GSRD 2.0 project to enable Macronix flash. User is required to regenerate and rebuild the HW/SW project after update the settings.
1. In GSRD u-boot software project main.c file - specify Macronix as the SPI Flash manufacturer in function qspi_flash_cntl_read_fifo_dis()
- JEDEC_MANUFACTURER_ID_WINBOND (Default)
- JEDEC_MANUFACTURER_ID_MACRONIX
Update SPI flash manufacturer in main.c()
Reference: FPGA-RD-02300 Section 8.2. Using different SPI flash manufacturer
2. Update u-boot QSPI configuration to Macronix
- Follow step 4 in FPGA-RD-02300 Section 10.3. QSPI Configuration for U-Boot, choose Macronix SPI flash support.
- Or Press Space > Select Macronix QSPI > Press Space > Unselect Winbond
Menuconfig - Select Macronix QSPI

GSRD 1.0 \u2013 How to enable GSRD to boot from Winbond flash
GSRD 1.0 deliverables is target to CertusPro-NX Versa Board with Macronix flash.
Please follow below steps to modify default GSRD 1.0 project to enable Winbond flash. User is required to regenerate and rebuild the HW/SW project after update the settings.
1. In GSRD u-boot software project main.c file \u2013 change QUAD_SPI_MODE to STANDARD_SPI_MODE to enable single SPI mode for Winbond flash.
This is due to Winbond flash Quad Enable operation is not compatible with GSRD1.0 QSPI driver operation.
Users need to enable Single SPI mode and rebuild the software Image.2. Radiant Programmer: QSPI programming \u2013 specify Winbond settings in \u201CSPI Flash Options\u201D
