[U-Boot-Users] RFC: U-Boot version numbering
by Wolfgang Denk 06 Aug '08

06 Aug '08

Hello, I would like to get your general opinion about changing the U-Boot version numbering scheme. To be honest, I never really understood myself how this is supposed to work and if the next version should be 1.3.4 or 1.4.0 or 2.0.0, i. e. which changes / additions are important enough to increment the PATCHLEVEL or even VERSION number. I therefor suggest to drop this style of version numbering and change to a timestamp based version number system which has been quite successfully used by other projects (like Ubuntu) or is under discussion (for Linux). My suggestion for the new version numbers is as follows: VERSION = 1 (at least for the time being) PATCHLEVEL = current year - 2000 SUBLEVEL = current month Both PATCHLEVEL and SUBLEVEL shall always be 2 digits (at least for the next 91+ years to come) so listings for example on an FTP server shall be in a sane sorting order. If we accept this system, the next release which probably comes out in October 2008 would be v1.08.10, and assuming the one after that comes out in January 2009 would be named v1.09.01 Comments?

Hard- ware has limitations, software doesn't. It's a real shame that Turing machines are so poor at I/O.

[U-Boot-Users] [PATCH 1/2] Update linux bootm to support ePAPR client interface

Re: [U-Boot-Users] [PATCH] Fill in remaining MTD driver data for OneNAND (take #2)
by Fathi BOUDRA 06 Aug '08

06 Aug '08

> Don't cast the return of malloc. ok. > Why not just declare a static array? I tried with a static array but it doesn't give the expected result (a quick test with onenand info command returns an empty mtd name), so I used a pointer. > It'd be better to use snprintf, even if you're pretty sure it won't > overflow. I tried it too :) U-Boot doesn't have snprintf or asprintf or I missed something. Do I need to re-submit the patch only for cast ? cheers, Fathi

[U-Boot-Users] Design Recommendation and Help with Issues
by Jatin Sharma 06 Aug '08

06 Aug '08

I am running U-Boot version U-Boot 1.3.1-rc1 on my board that has a Broadcom network switch. My goal is to initialize this switch at the bootloader level and be able to tftpboot a Linux kernel from one of the ethernet ports of this switch. As _I_ understand, there are two ways to initialize the switch from u-boot. First ===== Theory: Link the switch driver software with the u-boot.bin and flash it on the board. Switch driver's entry point would be called somewhere in u-boot to initialize it. Size of the u-boot.bin will increase and the u-boot partition on the NOR flash will need to be updated to accommodate the new binary size. Practice: After I linked the driver software with the u-boot.bin, the board didn't boot any further after u-boot got relocated to RAM with this following message: "Now running in RAM - U-Boot at: 0ff6d000" I did the following to link switch driver library (MDK_BLIBS) with u-boot in Makefile: $(obj)u-boot: ......... --start-group $(__LIBS) $(MDK_BLIBS)--end-group $(PLATFORM_LIBS) \ ......... Switch library is compiled with same TEXT_BASE and other flags as that of u-boot. Second ====== Theory: Build the network switch driver as a u-boot application, flash it on a free partition on the NOR and after u-boot has booted, it will somehow do the following to initialize the network switch. cp.b 0xfff90000 0x40000 0x5bfac go 0x00040418 Practice: The above two commands worked to initialize the switch. I still need to understand how to run these command automatically after the u-boot has booted. Questions: 1.) Which design is recommended, first or the second? Second is easier for me to implement as I don't have to change the partition sizes but could easily be overlooking some obvious problems. 2.) If the first design is recommended, I would need to resolve the u-boot-not-booting issue when the binary is compiled with switch driver. Any suggestions where to look? Thanks, Jatin

[U-Boot-Users] SAM-BA 2.8 NAND scrub equals all blocks bad
by Darrik Spaude 06 Aug '08

06 Aug '08

I have been trying to recover from ignorance on my part when I used Atmel's SAM-BA 2.8 utility to scrub the NAND on my board. Scrubbing should be more thorough than erasing, right??? Oops. So, I thought that maybe I could use u-boot (pulled from DataFlash via AT91SAM9G20) to recover my NAND, but I haven't had any success. U-boot (1.3.3) has scrub and erase capabilities, but all efforts still result in all blocks being bad. I found a "createbbt" patch and that still results in all blocks being bad. Any ideas on how to recover the NAND to a state where u-boot can determine REAL bad blocks? Or did the Atmel SAM-BA utility truly destroy the NAND and I should replace it? Thanks for the help, Darrik

[U-Boot-Users] [PATCH] sequoia uarts
by Steven A. Falco 06 Aug '08

06 Aug '08

I have verified that the Sequoia (440EPx) does not have its UARTs properly configured. The attached patch corrects this by setting three bits in SDR0_PFC1 to enable 4-wire mode, and to select cts/rts functionality for the UARTs. Also, I modified the GPIO settings for pins 34-37 to conform to the tables in section 31 of the 440EPx users manual. Here is a dump of the registers once the patch was made. I've verified that these match the users manual. Also, my Sequoia board works. :-) => getidcr e.f 4101 000e.000f-4101 Read 034c100f => md.l ef600c00 1 ef600c00: 00000000 .... => md.l ef600c04 1 ef600c04: d6000000 .... => md.l ef600c08 1 ef600c08: 52180000 R... => md.l ef600c10 1 ef600c10: 00000000 .... => md.l ef600c40 1 ef600c40: 00000000 .... => md.l ef600c38 1 ef600c38: 04010000 .... => md.l ef600c30 1 ef600c30: 00405550 .@UP Signed-off-by: Steven A.

[U-Boot-Users] Ethernet phy driver is not working in u-boot
by tomydevasia 06 Aug '08

06 Aug '08

Hi, I am currently working u-boot for AT91SAM9260 based board. In this board we are using LXT971A as phy rather than davicom dm9161a as in AT91SAM9260-EK. We have u-boot-1.1.5 version with AT91SAM9260 support, but it is having phy support only for Davicom dm9161a . So we have changed the phy driver by making appropriate modifications in Davicom dm9161 to make suitable for LXT971A . We have downloaded the image in flash. We have connected one ethernet cross cable between the board and one PC.After rebooting we are observing the following 1) Initially auto negotiation is happening with the PC.And tried to ping the PC from u-boot. 2) While pinging from the u-boot, the request is not coming to the Computer(We checked up with Ethernet sniffers like Ethereal), 3) In u-boot after ping request it will wait for the reply from the other side, it is receiving packets from my Computer (It is not the reply of ping, some other broad cast message). So my conclusion is that, the Ethernet packets from U-boot is not reaching up to the Computer but packets from the Computer is receiving there inside the board. I don't know any one you face the same problem. So I request you to reply if you have any clues to solve the issue.
