Re: [U-Boot] Porting u-boot for MPC8280 based board.

...

 Yes These frequency and flash base address are correct to my board.

SMC2 pins PA9-TX and PA8-Rx, I Checked BRG and clock routing is matching to board.

Then you need a debugger.

...

I have BDI 2000 tool, but its not connecting to board.

This is a problem that should be fixable. Keep in mind that the MPC82xx can come up in different modes, depending on if there is a valid HRCW in flash or not. This can change the start address, too. Try both high and low boot configurations.

For reset circuitry HRCW is there. In hardware also its considered. if i Want to try for high boot have to change TEXT_BASE address?
