[U-Boot-Users] 5200lite start

I am starting with Motorola 5200lite board. Which onfig target should I provide to makefile to create u-boot image for this board. Over DULG FAQs I got to doc suggesting $ make 5200LITE_LOWBOOT_config but I do not find it in the u-boot 1.1.2 distribution. Regards.

Thanks for your kindness! I just wanted to install the U-Boot on the Bubinga405EP evaluation board,but for case sensitive issues I couldn't pass the building process,so I turned to U-boot mail list for help. Now I have passed building procedure and I will do some modification about the u-boot so that it can be run on other boards designed by us. ===== James.Zhou __________________________________ Do you Yahoo!?

[U-Boot-Users] Problems during board configuration of U-boot1.1.2!
by liangdongzhou liangdongzhou 20 Feb '05

20 Feb '05

I had just been in porting U-Boot1.1.2 to AMCC's Bubinga405ep Eval board.But after I had generated PPC_4xx-gcc cross-compiler and do board configuring,some problems appeared on the screen: [root@sunriver u-boot]#make bubinga405ep_config make:*** No rule to make target"bubinga405ep_config". Stop I don't know what's wrong with the u-boot,for I had checked the config.h and no errors found.Help me pls! James.Zhou __________________________________ Do you Yahoo!?

Re: [U-Boot-Users] IBM/AMCC 440EP ethernet question
by Miles Gazic 18 Feb '05

Bradley, Apart from the typo I posted about in my previous message, there is one bit field that looks different between the 405GP header file and what the 440EP has. There is a #define for EMAC_ISR_SYE in the 405 header file, and it's at the same place that something called ALE (alignment error) is at in the 440EP user manual I have. That bit is set high in the 405 code when the speed is supposed to be 100Mbps. I don't know what the reprecussions of setting it high are if it really is ALE and not SYE. But it can't be too important if it's worked like that so far for you. Do you happen to know what PHY you are using? Our Broadcom AC101L can do both RMII and MII, the hardware guy thinks all he might have to do is pop in a 50MHz crystal instead of the 25MHz one we have now. I think it might be worthwhile for me to try that, at least I'll be travelling down the road more well travelled. Thanks, Miles

I found one part of the problem. The 0x8100 I was writing included the reset bit. When I take that out I can set the command register and read it back. We can now get a link 10Mbps, 100Mbps doesn't work. Auto-negotiate sometimes doesn't work, and sometimes ends up at 10Mbps speed even though both sides should do 100Mbps. We are making progress now at least. I went through the register definitions and bit field definitions again to see if any I am using aren't right for the 440ep, and I noticed that EMAC_TRTR_128 is 0x01000000 for both 440gx_enet.h and 405gp_enet.h in U-Boot. For the EP, only the 5 most significant bits aren't reserved, and the value in my user manual for EMAC_TRTR_128 is binary 00001. Seems likely that it's the same for other 440s and 405s, and someone made a typo. From the most significant end of the register, 00001... = 0000 1000 = 0x08 != 0x01. It's page 897 of ppc440ep_um.pdf, and that's the only user manual I've got. If anyone has another 440 or 405 user manual handy and would like to check this out I'd appreciate it. Otherwise I'll download a couple other user manuals and if they match mine I'll figure out how to submit a bug report.

RE: [U-Boot-Users] memory sizing(440GX)
by Barbier, Renaud (GE Infrastructure) 18 Feb '05

thanks .did not know that there was code. should this function find the correct RAM size. I have tried this get_ram_size(0, 512MB) on a board that has 256MB and it does not return the proper size (256MB). I guess I need to test incrementally for the memory size.

[U-Boot-Users] IBM/AMCC 440EP ethernet question
by Miles Gazic 18 Feb '05

18 Feb '05

I'm using a 440EP with MII mode selected, and a Broadcom AC101L phy. Autonegotiation was failing, so as an experiment, I tried replacing the start of autonegotiation in 440gx_enet.c, with setting the speed manually. I did a miiphy_write to PHY_BMCR (the control register) with 0x8100 (which should specify 10mbps, full duplex). The miiphy_write returns 0 which means it doesn't think it failed, but when I look at the value in the control register as spit out by miiphy_dump, it is still 0x3000 (which is 100mbps and half-duplex), which is the same value I always see there. I don't think this is just a U-boot problem because I can duplicate what's happening using just a Abatron BDI2000. When I write a 0x81002400 into the EMAC_STACR register (which should set the control register of the phy to 0x8100), and then write a 0x00001400 into EMAC_STACR (which should request a read of the same register), and then look at the EMAC_STACR register in the debugger, it has the same 0x3000 as I see in U-Boot. It seems likely to me though that if anyone has gotten the 440EP to work with MII in U-Boot, then they might be able to shed some light on what is going wrong for me. Any advice is appreciated, Miles
