U-boot start up from DRAM using Code Warrior

[tukimukai_th10]

I want to boot a custom board with T1014, but my boot device is not supported by Code Warrior flash programmer and u-boot cannot be written to the boot device. (MT29F4G SPI NAND Flash is mounted on the custom board.)
So, I want to boot u-boot from DRAM using JTAG. Is it possible to boot u-boot from DRAM using codewarrior?

thanks in advance.

Hello, Yiping,

Thanks for your reply.

I know CodeWarrior IDE flash programmer supported MT29F4G connected to IFC/eLBC interface. but, our custom board NAND Flash is connected to SPI Interface.(The full device name is MT29F4G01ABBFD12-AATES.)

Thanks,

Hirobe

You could refer to C:\Freescale\CW_PA_v10.5.1\PA\PA_Tools\FlashToolKit\SPI_Example to develop SPI flash program algorithm for MT29F4G.

Hello hirobe motoharu,

The flash device MT29F4G is integrated in CodeWarrior IDE. You could calculate IFC timing referring to IFC Controller Configuration on QorIQ Custom Boards , then use these parameters to modify CodeWarrior initialization file.

Then please refer to https://community.nxp.com/docs/DOC-100896 to do flash programming.

Thanks,

Yiping
