Hello All, Thanks a lot everyone for all the inputs regarding my earlier query on CFG_FLASH_BASE, CFG_MONITOR_BASE< TEXT_BASE. I have changed the value of mt TEXT_BASE to 0xFFF00000 as suggested and it works. But there is another problem now. While debugging myu customised U-boot code for 8266 based PMC card i am able to jump from the first instruction in start.S i.e "li r21, BOOTFLAG_COLD" to the second instruction "nop".But after the "nop" instruction the program counter starts decrementing and goes backward into unknown memory locations. Can anyone tell me why this is happening and how i can correct it.

Thanks & regards, Apoorv Sangal.

Can anyone please let me know how to set the following parameters:-

Our boot flash is 512kb and its base address will be 0xFFF80000. We are using HRCW = 0x04023644. (Boot address = 0xFFF00100)

1.How to set the cfg_flash base. 2.How to set the cfg_monitor base

Run a text editor, open include/configs/<your_bord_name>.h, edit the #defines for CFG_FLASH_BASE and CFG_MONITOR_BASE, save the new file, exit the editor.

3.How to set the TEXT_BASE in config.mk

Run a text editor, open board/<your_bord_name>/config.mk, edit the line that reads "TEXT_BASE = ...", save the new file, exit the editor.

What exactly was the part of this actions you had problems with?

Best regards,
