[U-Boot-Users] [PATCH] support for CF/IDE on PCMCIA for PXA25X
by Christian Pell 13 Aug '05

Hi, I tried this with some different CFs with FAT file-systems on them. There is a README in the patch itself that goes in documentation directory. Bye, -- Christian Pellegrin <chri(a)ascensit.com>, <c.pellegrin(a)eurotech.it>, <chri(a)infis.univ.ts.it>, <c.pellegrin(a)exadron.com>

Re: [U-Boot-Users] Support for Samsung 1Giga bit NAND device
by Laurent Mohin 01 Jun '05

Andy, U-boot 1.1.0 doesn't provide support for NAND flash with a page size of 2K-byte instead of 512 byte (and you're right, theses devices require special handling). Pantelis Antoniou submitted a patch on 2004-04-30 which seems to manage these new chips, but I don't think it has been added to the latest CVS tree. By the way, Samsung also offer 1 Giga bit devices with a 512 byte page size (K9K1G08UOM - Manufacturer ID : 0xEC, Chip ID: 0x79). Hope this helps, Laurent Andy Hawkins <a.hawkins(a)cabletime.com> Sent by: u-boot-users-admin(a)lists.sourceforge.net 14/06/04 13:40 To: u-boot-users(a)lists.sourceforge.net cc: Subject: [U-Boot-Users] Support for Samsung 1Giga bit NAND device Hi, Can anyone tell me if U-Boot has support for the Samsung 1 Giga Bit NAND devices (Manufacturer ID: 0xec, Chip ID: 0xf1)? I understand these devices have an unusually large block size, that needs special handling. Is this correct? Thanks.

[U-Boot-Users] Environment in flash rather than EEProm
by Andy Hawkins 11 Feb '05

11 Feb '05

Hi all I'm using a PPChameleonEVB, and am trying to move the u-boot environment into flash. I've modified the include/configs/PPChameleon.h file as follows: #define CFG_ENV_IS_IN_FLASH 1 #define CFG_ENV_ADDR 0xFFFFA000 #define CFG_ENV_OFFSET (CFG_ENV_ADDR - 0xFFFC0000) #define CFG_ENV_SIZE 0x2000 I've added some debugging into the section where it reads the environment, and I'm seeing the following: U-Boot 1.0.2-adh-2004/03/29 (Mar 30 2004 - 13:40:38) CPU: IBM PowerPC 405EP Rev. B at 133.333 MHz (PLB=133, OPB=66, EBC=33 MHz) IIC Boot EEPROM disabled PCI async ext clock used, internal PCI arbiter enabled 16 kB I-Cache 16 kB D-Cache Board: ### No HW ID - assuming PPChameleonEVB I2C: ready DRAM: 32 MB Top of RAM usable for U-Boot at: 02000000 Reserving 189k for U-Boot at: 01fd0000 Reserving 256k for malloc() at: 01f90000 Reserving 128 Bytes for Board Info at: 01f8ff80 Reserving 48 Bytes for Global Data at: 01f8ff50 Stack Pointer at: 01f8ff38 New Stack Pointer is: 01f8ff38 Now running in RAM - U-Boot at: 01fd0000 FLASH: 4 MB env_relocate[204] offset = 0x2010000 env_relocate[216] embedded ENV (before reloc) at fffd9474 env_relocate[218] embedded ENV (after reloc) at 01fe9474 U-Boot relocated to 01fd0000 NAND:Probing at 0xff000000 32 MB ### main_loop entered: bootdelay=5 ### main_loop: bootcmd="<UNDEFINED>" => As you can see, the address of the environment before relocation is 0xfffd9474. Shouldn't this be 0xFFFFA000? Is there anything else I need to do to force the location of the environment into the required place? It looks like the address of the environment is based on the location of the 'environment' variable in common/environment.c. Do I need to change the LD script to force this variable to a certain location? If so, can anyone help with what I need to do (I'm not familiar with LD scripts yet). Many thanks. Andy

Hi, I am using smc91111.c driver of u-boot. all my network functionalities are working well. i am able to ping an other ip address and i get a message that the host is alive or not. Only problem is, when someone pings the target ip (my network card ip), it says destination not reachable. Is this really a problem? if so, pls help me solving it. regards vidya

[U-Boot-Users] Generating b-records for DragonBall i.MX
by Steven Scholz 10 Oct '04

10 Oct '04

Hi there, I just hacked a simple script that converts u-boot.bin into a text file containg processor init code, SynchFlash programming code and U-Boot data in form of so called b-records. This can be used to programm U-Boot into (Synch)Flash using the Bootstrap Mode of the MC9328MX1/L 0AFE1F3410202E2E2E000000002073756363656564/ 0AFE1F44102E0A0000206661696C656420210A0000/ 0AFE100000 ... MX1ADS Sync-flash Programming Utility v0.5 2002/08/21 Source address (stored in 0x0AFE0000): 0x0A000000 Target address (stored in 0x0AFE0004): 0x0C000000 Size (stored in 0x0AFE0008): 0x0001A320 Press any key to start programming ... Erasing ... Blank checking ... Programming ... Verifying flash ... succeed. Programming finished. So no need for a BDI2000 anymore... ;-) This is working on my MX1ADS eval board. Hope this could be useful for someone. (Maybe we even want to include this into the tools directory.) Steven

[U-Boot-Users] Binary file cat
by Adam Bezanson 03 Aug '04

03 Aug '04

Hi, I have ported u-boot to my arm920t based system. I have a unique situation in that my processor requires a binary header to be placed In front of u-boot.bin before it is burnt into flash. If the processor doesn't find this header in flash it will not boot out of flash. Currently I have the header file as a separate file in the root directory and when I finish a new compile I have a shell script which Simply does a 'cat header.bin u-boot.bin > out.bin'. I'd like to get away from this and add it to the Makefiles so for my board I don't have to run this script every time. Before I go editing a top-level Makefile, I wanted to ask for advice on how I should go About doing this? Anything I can do in my board-specific directory would make me feel better. Suggestions? Thanks, Adam
