Hi
we are trying write and read operations in compact flash . For 16 bit data access we should get the device id 84 8A. instead of 848A , there we read only 84. remaining LSB 8 bits are not read.
When board boots from NAND flash we are getting some warning, is mentioned below.
WARNING: both IDE and NOR flash are enabled, but share pins.
Disable IDE for NOR support.
We are accessing only CF interface. the PINMUX0 & Programmable Registers also configured for Compact flash card only as per the ATA/CF Application notes SPRUE21.
The chip select jumper j2 is connected for FLASH. But the CS2 we are not using. How to resolve this problem?
I have to work with compact flash means, should i disable nor flash? this could be the problem for compact flash not work properly?
Please guide us to store the video using compact flash card..
for your reference, i attached the log file when dm6446evm boots..
regards,
azhagiri
