Hi,
I encounter the nand read speed issue during my development, the detail procedure as below:
1.I used the Micron Large page x16 NAND for development.
2.In \u-boot-2010.06-psp04.00.00.10\arch\arm\include\asm\arch-ti81xx\Mem.h file , I modified the M_NAND_GPMC_CONFIG5 bit 0-4(which means RDCYCLETIME). from 1e(default) to 07(fast speed as calculated) .
3.I print the value of M_NAND_GPMC_CONFIG5 ,lt's vaule changed as i modified.
4. I through Oscilloscope I observed between both setting(1e and 07) TOE(which means read cycle time) are around 632 ns.looks like the change doesn't take the effect for the hardware.
any one encounter the same issue? whether any other setting i need to do to solve this issue?
