* [U-Boot-Users] Patch for NAND Booting on SMDK2410 @ 2004-01-09 14:18 Markus Pietrek 2004-01-09 16:09 ` Matt Matoushek 2004-02-08 20:16 ` Wolfgang Denk 0 siblings, 2 replies; 6+ messages in thread From: Markus Pietrek @ 2004-01-09 14:18 UTC (permalink / raw) To: u-boot Hi folks, here is a patch to enable U-Boot 1.0 to boot from NAND/SmartMedia cards. smdk2410.h must include the line '#define CONFIG_BOOT_NAND 1" and the resulting u-boot.bin must be copied to the first SmartMedia sectors (with a JTAG tool for example). The first sector of the SmartMedia card should also be marked as "Defect". With J33 and J34 closed the board should then boot from SmartMedia. This first version is very simple as U-Boot is linear on the SmartMedia and don't allows a filesystem. Later version may include placing U-Boot on a filesystem. This patch also includes code for clearing the BSS segment. This is not the same code Larsen submitted this morning :-( Bye, -- Markus Pietrek FS Forth-Systeme GmbH Phone: +49 (7667) 908 145, FAX +49 (7667) 908 221 -------------- next part -------------- A non-text attachment was scrubbed...

I am developing a platform based on the s3c2410 and have been using U-boot (booting from NOR) as a development boot-loader since I can easily tftp new code, file systems, etc. For production use I have intended on using a modification of the ADAM boot-loader provided by Samsung, mainly because CFG_CMD_NAND isn't implemented yet in U-boot for the smdk2410. The NAND boot patch gives me a potential alternative. Am I correct about status of CFG_CMD_NAND for u-boot and the smdk2410? If I am correct, is there anyone out there working on this? If so, would you like any help with that development? -- Matt Matoushek Invocon, Inc. www.invocon.com 281-292-9903 mmatoushek at invocon.com ^ permalink raw reply [flat|nested] 6+ messages in thread

With this patch I demonstrated that we are able to boot from it. But I haven't started yet to port cmd_nand.c to the s3c2410 hardware nand support feature. This will come up in about two months again. cmd_nand.c though needs to be rewritten, mainly the commands NanD_Command, NaND_Address, nand_write_ecc, nand_read_oob etc. Bye, -- Markus Pietrek FS Forth-Systeme GmbH Phone: +49 (7667) 908 145, FAX +49 (7667) 908 221 ^ permalink raw reply [flat|nested] 6+ messages in thread
