Have anyone ever get experiences on access of SPI-NOR flash for i.MX6DL Sabre AI?
I'm trying to leverage existing ECSPI and flash driver from i.MX6q Sabre Lite, the whole SPI phase transfer process status is good, but all data read from flash is 0xff (including data content and flash status itself).
After taking a serious look at back of CPU board, there is a wire-jumper just at back of SPI-NOR chips. I'm wondering is there any special hardware configuration required?
Thanks in advance
