Christian: It looks like you have your memory controller (BRx/ORx) configured for 32 bits but your actual memory width is 16 bits so the processor is reading 32 bits on every bus cycle, half of which are garbage. gvb > -----Original Message----- > From: u-boot-users-admin(a)lists.sourceforge.net > [mailto:u-boot-users-admin@lists.sourceforge.net]On Behalf Of CG > Sent: Thursday, May 27, 2004 2:46 PM > To: Wolfgang Denk > Cc: u-boot-users(a)lists.sourceforge.net > Subject: Re: [U-Boot-Users] flash erase > > > I use only one 16-bit flash device.

[U-Boot-Users] running U-boot on ML300 board??
by Abdelmajid Bouajila 27 May '04

Hello, When running U-boot on ML300 board, I don't receive any character on the serial port. I worked so: *I downloaded a reference design given by xilinx. *With the xparameters.h, I compiled U-boot *I put U-boot in \sw\os\linux\kernel....I rename it on zImage.embedded. *I generate my ace file, and nothing happens when running it on the ML300 board. Have I done a mistake? Thanks Abdelmajid

The values given in the example in the README are for PowerPC; for ARM or other architectures you must adapt these to your system's requirements.

Hi, We would like to boot our system using a USB 2.0 memory stick. Does u-boot support any USB 2.0 controllers such as the CY7C67200? Is anybody working on adding support for USB 2.0 for an off chip controller? regards, Shlomo Kut Vyyo Ltd POB 45017 Jerusalem 91450 Israel +972-2-5889822 ********************************************************************** The information transmitted is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.

[U-Boot-Users] Help U-boot without dhcp,bootp

Hi there... I m very newbie to U-boot. I installed U-boot 1.1.1 in my King canyon Board (Intel's ixp425 Processor). I can able to see the following mesg while reseting the Board power. U-Boot 1.1.1 (May 4 2004 - 13:15:14) U-Boot code: 00F80000 -> 00F90D9C BSS: -> 00F922AC RAM Configuration: Bank #0: 00000000 16 MB Flash: 32 MB In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 ## Booting image at 50040000 ... Bad Magic Number => help The help list displays only loadb,loads downloding commands. I dont know how to download the Linux kernel from my PC to Board. But In U-boot's Online manual deals booting the board via BOOTP, DHCP.Those options (bootp,dhcp,rarpboot,tftpboot) are not available in my bootloader. I compiled the U-boot code by following the below steps. make ixdp425_config make Tell me what should i do to get the above options and how to download my kernel,ram disk to my board ?. Is it possible to convert my zImage into BIN format... (I think .srec format occupies more memory space). Thanks in Advance. Thanks Prakash

[U-Boot-Users] PXA resume
by Matej Kupljen 27 May '04

27 May '04

Hi I've implemented resume into the U-Boot which can resume Linux from sleep, but I have a "strange bug". Maybe someone have seen this and can help me. We have two identical development boards, the only difference is the amount of SDRAM on board. One has 32MB and the other one has 64 MB of SDRAM. When configuring the memory controller the code checks the value of the DIP switch on board and configures the memory controller for 32 MB or 64 MB of SDRAM. The difference between those configurations is, that when configuring for 64 MB I have to turn on the SA1111 addressing (in the MDCNFG), the refresh interval and the number of row address bits. I can resume the board with the 32 MB, but cannot resume the board with the 64 MB. If I add a single NOP instruction (or any other instruction, like LDR, MOV, ...) before (or just after) the code that reads the value of the DIP switch, I can resume the board with 64 MB and not the board with 32 MB. I have attached the memsetup.S. What might be wrong? Regards, Matej
