Hi OPakh,

If you want to enter the QUAD mode, you need to enable the QUAD mode first.

This is the step to enable the QUAD mode:

set flash_cmd_setting [expr {$base + 0x1c}]

set flash_cmd_ctrl [expr {$base + 0x20}]

master_write_32 $mp $flash_cmd_setting 0x00000035

master_write_32 $mp $flash_cmd_ctrl 0x1

I hope this will help.

Thanks😉
