I am a new developer on Atmel. Would you give me some advice on this? Thanks a lot.


Downloading Verify failed on J-Link GDB Server  as u-boot was loaded to customed board  based on Atmel SAMA5D2 Xplained Ultra.

but in the same develop environment, the same u-boot file can be loaded successfully to Atmel SAMA5D2 Xplained Ultra,
and work/at91bootstrap-3.8.7/binaries/sama5d2_xplained-dataflashboot-uboot-3.8.7.elf can be loaded and run successfully to customed board  and Atmel SAMA5D2 Xplained Ultra.

The DDR size of customed board  is 256M Byte, one piece of DDR. and the DDR size of Atmel SAMA5D2 Xplained Ultra is 512MByte, two pieces of DDR.

Beneath is the files of u-boot I have changed.


static void ddrc_conf(struct atmel_mpddrc_config *ddrc)



/*  #define CONFIG_SYS_SDRAM_SIZE        0x20000000  */
#define CONFIG_SYS_SDRAM_SIZE        0x10000000

the attachments are log files of JLinkGDBServer.  
gdbserver-customboard-1.txt and gdbserver-customboard-2.txt are logs for customer board we developed.
gdbserver-AtmelSAMA5D2Xplain.txt is log for Atmel SAMA5D2 Xplained Ultra board.
