First of all, I compiled the driver of SPI NORFLASH into the kernel,and the system up and running from NANDFLASH,then I found that the SPI NORFLASH normally detectable, file device nodes(/dev/mtd2,/dev/mtdblock2), as follows: mxs-spi mxs-spi.0: Max possible speed 24000 = 24000000/2 kHz mtd_dataflash spi1.0: AT45DB321x (4224 KBytes) pagesize 528 bytes, OTP mxs-spi mxs-spi.0: at 0x80014000 mapped to 0xF0014000, irq=84, bus 1, DMA ver_major 4 After I downloaded mtd_debug into the system, this command can be burned the imx28_ivt_linux.sb into the SPI NORFLASH.I jumper to the SPI2 go to start the board(0010), the SPI Flash connected ssp2, but did not start any of the information. I understand: 1.Since I can boot from NANDFLASH, so that imx28_ivt_linux.sb no problem. As long as the correct jumper, they can start from the SPI FLASH. 2.mtd_dataflash spi1.0: AT45DB321x (4224 KBytes) pagesize 528 bytes, OTP This information is spi1.0, I obviously use SSP2, here I can not understand. Who can give me some tips?Thanks!!!!!
