RE: [U-Boot-Users] Can U-Boot be divided into TWO stages
by Woodruff, Richard 17 Jun '04

17 Jun '04

In another email to me, he indicated this was for an OMAP processor. Someone I work with already has done this and its working. Most of the u-boot code has been removed. Enough of the structure exists, so it feels like a u-boot build environment (and more or less looks like one also). We don't plan to merge it as it wouldn't make sense. We will provide it to people who want it for OMAPs and NAND booting, it is of coarse GPL. The when its easily available is probably the only minor issue.

[U-Boot-Users] supported flashes?
by Bastos Fernandez Alexandre 17 Jun '04

17 Jun '04

Hi to all, It's the first time I write to this list. I am involved now in a new design based the MPC8272 processor. I have choosen U-boot as my booter am by now I am trying to select the flash memory, so I have to determine which are supported. And this is not very easy, because I couldn't find any doc related to hardware support. I have looked at the code and I found lots of files about flash support. In particular: drivers/cfi_flash.c board/mpc8260ads/flash.c common/flash.c common/env_flash.c I have concluded that cfi_flash.c gives support for all those flashes which implements the JEDEC CFI interface with AMD or Intel command sets, and mpc8260ads/flash.c gives support for the flash in the ADS board (which is not CFI at all). Am I wrong? What about the other files? Is there anywhere a list of supported flashes? In conclusion, can i suppose that any CFI flash with the appropriate command set will be supported by u-boot. Thanks to all Alex Bastos

[U-Boot-Users] u-boot Tulip DECchip support
by Yusuf Ibrahim Özkök 16 Jun '04

16 Jun '04

Hi, I'm using a Sandpoint board with X3 (MPC8245) unity CPU card. Sandpoint does not have an ethernet controller.And since I have a PCI DECchip 21x4x Ethernet controller I want to use it with sandpoint board. I'm able to use this ethernet card with my linux image, it works fine, but I couldn't add this to u-boot image. So I'm dowloading the linux image by using "loadb" or "loads" commands via serial channel and it tooks to much time. You can see my previous tryings below. Is there anybody who has used this ethernet controller with Sandpoint? Or do you have any suggestion for my problem. Regards yio P.S: Below, there are previous messages between I and Wolfgang. Since I was not aware of using this list I have sent e-mails directly to Wolfgang. Thanks to him for his recommendations about the problem and warnings about using this list. ------------------------------------------------------------------------------------ Hello, in message <000b01c44ebe$9f0193d0$aa06010a(a)aselsan.com.tr> you wrote: > > First of all, Thank you very much for your help.

OK, since it seems to Maybe I was not clear enough. "CFG_CMD_NET" is not a #define you should set yourself; you should make sure that "CFG_CMD_NET" is included (i. e. used) in your definition of the CONFIG_COMMANDS definition. > So as a result, my DECchip Ethernet card is still not working with > u-boot.

RE: [U-Boot-Users] [PATCH] smc91111.c gcc-3.3.3 warning fix
by Woodruff, Richard 16 Jun '04

goto's while ugly do have a good usage in error unwinding. Most of the C tomes say this and I agree... I didn't look closely at this specific situation in the 91111 and all of it's context, but from the patch it appeared to be an error path. Leaving with a return may be the cleaner thing to do here. Removing goto's is generally good, but I wouldn't go out of my way to recode in instances when they are the most efficient way to go.

Even toward the more trivial, I believe that Wolfgang or someone pointed out before that adding a ';' after the target goto label will also remove the warning.

[U-Boot-Users] timer exception...
by Seingier François-Xavier 16 Jun '04

16 Jun '04

hello, I am trying to port u-boot to an EP405 board from embedded planet. I have never been so close to the end (sigh!) but it seems I'm too tired right now to spot out any more bugs... This time, I can't figure out what may have gone wrong: the timer exception doesn't seem to increase the timestamp variable. I looked around in a few files (start.S, exception.c, ppc_asm.tmpl...) but I must admit I've no idea what I've been missing. Any clue? thanks in advance, François-Xavier SEINGIER
