[U-Boot] Uboot with at91sam9G20ek

[Abhishek Ashtekar]

Hello,



I have spent now more than 2 weeks with  U - boot and want the network interface to work

so that tftpboot works but my current state seems not very encouraging.





A)   I am using the AT91SAM9G20EK board. I downloaded tried the U-Boot.2010.12.

     I have the following results (issues) when I try to build.





             1) make at91sam9g20ek_nandflash_config

                 make CROSS_COMPILE=arm-linux-



                Error 1: You need to define CONFIG_AT91FAMILY in your board config

                Action: Defined CONFIG_AT91FAMILY in the file /include/configs/at91sam9260ek.h

                Also defined CONFIG_AT91SAM9G20EK in the same file







2) Error 2: board.c:233: CONFIG_SYS_SDRAM_BASE undeclared

                Error 3: board.c:279: CONFIG_SYS_INIT_SP_ADDR undeclared

               Error 4: board.c:312: CONFIG_SYS_SDRAM_BASE undeclared



                 In the file board.c,

                #define CONFIG_SYS_SDRAM_BASE             0x00000000

                #define CONFIG_SYS_INIT_SP_ADDR              (CONFIG_SYS_TEXT_BASE - GENERATED_GBL_DATA_SIZE)







3) Error 5: Undefined reference to 'CONFIG_SYS_INIT_SP_ADDR' in file /arc/arm/cpu/arm926ejs/start.S



               Cannot find a work around



               Error 6: /drivers/spi/atmel_dataflash_spi.c:161: undefined reference to 'reset_timer_masked'

                Error 7: /drivers/spi/atmel_dataflash_spi.c:161: undefined reference to 'get_timer_masked'



                Why are these definitions removed in the 2010.12 build?







B) Initially I was trying the u-boot-2010.09.

   I want to use the MII interface instead of RMII.

   so #undef ed RMII and #defined CONFIG_MII and CONFIG_CMD_MII



   The Ping to self as well as host does not function at all despite of correct settings.

   I tried with putting debug outputs in various functions called.

   Actually no data is sentout TXD0 - TXD3 and no activity on the TX_EN or EX_ER.





   At the end, I get ping failed; host xx.xx.xx.xx is not alive.





  Can anyone guide me regarding the further line of efforts.





Thanks a lot in advance.





Regards,

Abhishek
