Flash Programming, Zynq
Flash Programming, Zynq UltraScale+
Flash Programming fpr Zynq UltraScale+ MPSoC is currently only supported from u-boot and linux, SDK, Vivado and commandline tools can not be used.
Flash Programming, FPGA
Quad Enable Bit
For SPI Flash use in x4 mode Quad Enable bit must be set in nonvolatile Status Register. The commands for this depend the SPI Flash Vendor and/or Flash type. Vivado Flash Programmer when programming bit file generated with X4 option would set this bit automatically. All Trenz SoM's that need the Quad Enable bit set for proper operation are delivered with this bit set.
Spansion S256
Checking if the Quad Enable bit is set is possible from u-boot
> sspi 0 16 35
if result is 0002 then the nonvolatile Quad Enable bit is set
It is also possible to write the Quad Enable bit, 2 commands are needed
> sspi 0 8 06
> sspi 0 24 010002
The above will set Quad Enable bit in non volatile status register
