[U-Boot-Users] How can I save env values to NAND FLASH
by 최광일 28 Nov '03

28 Nov '03

Dear All Das U-Boot uses NOR FLASH for saving environment values for example IPADDR,GATEWAY and so on. I have a board with only NAND FLASH (SAMSUNG NAND FLASH 64M) without NOR FLASH and when I entered saveenv command to save environment values to NAND FLASH in U-Boot Some message returned and my values are not saved into NAND ======= Message ================ SMDK2410 # saveenv Saving Environment to Flash... Un-Protected 1 sectors Erasing Flash...Erasing sector 18 ... ok. Erased 1 sectors Writing to Flash... Flash not Erased Protected 1 sectors ===== End of Message =========== How Can I save environment values to NAND FLASH? Best regards

[U-Boot-Users] [PATCH] bootretry enviroment variable
by Pavel Bartusek 27 Nov '03

27 Nov '03

Hi, paste from the doc/README.autoboot CONFIG_BOOT_RETRY_TIME CONFIG_BOOT_RETRY_MIN bootretry environment variable These options determine what happens after autoboot is stopped and U-Boot is waiting for commands. CONFIG_BOOT_RETRY_TIME must be defined to enable the boot retry feature. If the environment variable 'bootretry' is found then its value is used, otherwise the retry timeout is CONFIG_BOOT_RETRY_TIME. CONFIG_BOOT_RETRY_MIN is optional and defaults to CONFIG_BOOT_RETRY_TIME. All times are in seconds. If the retry timeout is negative, the U-Boot command prompt never times out. Otherwise it is forced to be at least CONFIG_BOOT_RETRY_MIN seconds. If no valid U-Boot command is entered before the specified time the boot delay sequence is restarted. Each command that U-Boot executes restarts the timeout. end of paste from the doc/README.autoboot Currently is used function simple_strtoul() for parsing the bootretry enviroment variable. It fails if the bootretry is negative. The attached patch should fix it. -- Pavel Bartusek <pba(a)sysgo.com> Software Engineering SYSGO Real-Time Solutions AG | Embedded and Real-Time Software Lise-Meitner-Str.15 89081 Ulm, Germany Voice: +49-731-9533-1295 FAX: +49-731-94683-10 www.sysgo.com | www.elinos.com | www.osek.de --- u-boot.ori/common/main.c Thu Nov 27 19:25:30 2003 +++ u-boot/common/main.c Thu Nov 27 19:26:03 2003 @@ -505,7 +505,7 @@ char *s = getenv ("bootretry"); if (s != NULL) - retry_time = (int)simple_strtoul(s, NULL, 10); + retry_time = (int)simple_strtol(s, NULL, 10); else retry_time = CONFIG_BOOT_RETRY_TIME;

[U-Boot-Users] SCC3 on MPC852T
by Raghu 27 Nov '03

27 Nov '03

Hi All, I have a custom board housing MPC852T that has one SMC and 2 SCC controllers. I am able to configure the SMC for UART functionality. And the SCC4 for serial Ethernet functionality. But if I configure the SCC3 for Ethernet functionality I am losing the Serial prints aswell. Using the BDI I have been able to locate that the execution gets stuck in printf routines. I have defined the following in "commproc.h" ***************************************************** For SCC3 ------------------------------------------------- #define PROFF_ENET PROFF_SCC3 #define CPM_CR_ENET CPM_CR_CH_SCC3 #define SCC_ENET 2 /* CONFIG_SCC3_ENET */ #define PA_ENET_RXD (ushort)0x0010) /* PA 11 - Rx */ #define PA_ENET_TXD ((ushort)0x0020)/* PA 10 - Tx */ #define PA_ENET_RCLK ((ushort)0x1000 )/* PA 3 - CLK5 */ #define PA_ENET_TCLK ((ushort)0x2000 )/* PA 2 - CLK6 */ #define PC_ENET_RENA ((ushort)0x0200 )/* PC 6 - CD3 */ #define PC_ENET_TENA ((ushort)0x0004 )/* PC 13 - RTS3*/ #define PC_ENET_CLSN ((ushort)0x0100 )/* PC 7 - CTS3 */ #define SICR_ENET_MASK ((uint)0x00FF0000) #define SICR_ENET_CLKRT ((uint)0x00250000) *************************************************** Warm Regards, Raghu __________________________________ Do you Yahoo!?

[U-Boot-Users] U-Boot code checksum?
by Ted Schmitz 27 Nov '03

27 Nov '03

Does the U-Boot code generate and check a checksum or CRC on itself? I see code to verify CRC checksums on images that U-Boot loads into memory, but I do not see any code that checks the U-Boot image itself. If there is a function that checks the U-Boot CRC or checksum, could someone point it out to me? We burn the U-Boot code into a boot PROM and I need some way of verifying the boot PROM was burned correctly when the system powers up. I've written checksum generation and verification utilities in the past but would prefer to use the utilities that come with U-Boot if they exist. Thank you, ====================== Ted Schmitz Staff Engineer QLogic Corporation ted.schmitz(a)qlogic.com

[U-Boot-Users] Debugging U-Boot on 440GP
by Brian Padalino 27 Nov '03

27 Nov '03

I have a BDI2000 and a custom target board. I am can successfully connect to it and step through single instructions. I can also set a breakpoint at _start_440, but any breakpoints after that do not get noticed. I have the BDI setup for HARD breakpoints. Should I have it setup for SOFT instead? What I am seeing is that when I stop the CPU, it's either at 0x700 or 0x1400 -- both of which are defined in the kgdb.c file, but I don't know what they mean. Can anyone shed any light on the situation for me? I am very new to both the BDI and using gdb (but I learn quickly). Thank you, and much is appreciated. Brian Padalino

[U-Boot-Users] compact flash
by Ed Okerson 27 Nov '03

27 Nov '03

I am stumped, again. When u-boot comes up, "ide part" shows: DbAu1x00 # ide part Partition Map for IDE device 0 -- Partition Type: DOS Partition Start Sector Num Sectors Type 1 0 501760 f8 but fdisk in Linux shows: Command (m for help): p Disk /dev/hdg: 16 heads, 32 sectors, 980 cylinders Units = cylinders of 512 * 512 bytes Device Boot Start End Blocks Id System /dev/hdg1 1 9 2288 83 Linux /dev/hdg2 10 18 2304 83 Linux /dev/hdg3 19 980 246272 83 Linux Something else must still be in the wrong endian mode, but I can't figure out what it is.

[U-Boot-Users] how to start linux with u-boot?
by jxz 26 Nov '03

26 Nov '03

hi, I have successfully compiled u-boot-1.0.0 for my target board, and debbugged it by trace32.How can I debug u-boot to start linux? I do like this, I download u-boot to my target board and download linux at th same time on another SDRAM place. How to make right linux image? I have successfully done those step, make config; make dep; make Image. How u-boot start linux? where it call linux? Best regards Dannel Zhang

Wolfgang, Would stand alone application called though the uboot call interface need to be GPL'ed? I'm not sure that I would use it that way, but the flexibility it would provide would be useful.
