Hello Mingkai Thanks for you kind attention to my mail.
>Did you modify the the DDR memory size according to your DIMM in the >function fixed_sdram()? > Yes i know i have to do this. I fixed this via declaring a MACRO Globally. but for my first test case as i mentioned that i used the same Memory and same condition as they were before. The same memory (DDR1 DIMM 512MB) i am using before with the SPD read DDR setting. Indeed it is is neccessary to check @ the very first stage. :) thanks for your point but i am still in the trap :( -- Ashish 以上につきまして、ご確認の上宜しくお願い致します。 ★━━━━━━━━━・:*:*:・ ゜・:*:*:・★☆★ 東京エレクトロンデバイス株式会社 インレビアム開発センター「SFTG」 アガルワル アシッシュ 〒224-0045 神奈川県横浜市都筑区東方町1番地 TEL : 045-474-3549 FAX : 045-474-7060 E-MAIL : ashis...@teldevice.co.jp Home : http://www.teldevice.co.jp/ ★☆★・:*:*:・ ゜・:*:*:・━━━━━━━━━★ > > >> -----Original Message----- >> From: u-boot-boun...@lists.denx.de >> [mailto:u-boot-boun...@lists.denx.de] On Behalf Of AgarwalAshish >> Sent: Friday, May 15, 2009 3:27 PM >> To: u-boot@lists.denx.de >> Cc: ashis...@teldevice.co.jp >> Subject: [U-Boot] MPC8536DS Evaluation Board Force DDR >> Setting cannot bedone properly >> >> Hello All, >> >> I am Ashish Agarwal. >> >> Currently i am working on the MPC8536DS Freescale Development >> system evaluation and the Uboot development for a customized board. >> >> ------------------------------------------------------- >> Problem 1 : DDR Force setting >> ------------------------------------------------------- >> when i try to force setting of DDR parameter over 8536DS >> board through the >> #define CONFIG_SPD_EEPROM -> #undef CONFIG_SPD_EEPROM >> #define CONFIG_DDR_SPD -> #undef CONFIG_DDR_SPD >> >> the compile giver me error about "CONFIG_SPD_EEPROM is >> required" as this is written at the bottom place of >> include/configs/MPC8536ds.h file >> >> becuase we want to set forcly DDR parameters so I commented >> these lines too ==================================================== >> #ifndef CONFIG_SPD_EEPROM >> #error ("CONFIG_SPD_EEPROM is required") #endif >> ==================================================== >> DDR Force parameter were set as they were set when i complied >> the source with SPD setting.
