[U-Boot-Users] [PATCH] dhcp vendor fields - support opt bootfile, ignore tftp server
by Murray.Jensen＠csiro.au 12 Mar '06

12 Mar '06

This patch adds support for the dhcp vendor optional bootfile (#67). It also ignores the vendor tftp server name option (#66). Both of these are supplied by the DEC Tru64 Unix dhcp server (called "join"), and in the case of the bootfile, it is the only place the boot file name is supplied. There is a perfectly good, 128 byte, field in the main bootp/dhcp packet where the boot file name could have been stored, but it wasn't used - go figure. Cheers!

[U-Boot-Users] LXT971A PHY debugging on MPC8540 Custom Board
by Shirasat Girish-ags032 12 Mar '06

12 Mar '06

Hi , I have partially ported Uboot on one of our MPC8540 based custom boards. I am currently facing problems in bringing up the 10/100Mbps FEC interface. We are using the LXT971A PHY for the FEC interface. Well the problem is that , the MAC is putting out the data but the PHY is failing to put the data on the line. The PHY is successfully able to auto- negotiate. The MAC putting out data was confirmed by the MAC debug registers and by probing the Tx_EN,clock and TX_D lines. I carried out the MAC loop back test which passed . Then went on for the PHY internal loop back test. Well, when the loop back is enabled the MAC fails to transmit the frame successfully. The thing confusing me is that why the MAC frame transmission is getting affected when i enable the PHY loopback test. Any pointers will be very helpful. Regards, Girish

[U-Boot-Users] [Patch][CVS] Adjust CFG_CMD_ECHO as default ENV setting
by Sam Song 12 Mar '06

12 Mar '06

Hi list, Attached patch makes up a fix on CFG_CMD_ECHO. To avoid breaking exists boards, I adjust "echo" as a default command with aggreement of Wolfgang. For the sake of it's effect on all boards, pls check this one more carefully. About 12 boards related was fixed as well. Fix policy is that if CONFIG_CMD_DFL is used, CFG_CMD_ECHO shouldn't be redefined. Did I fix too much or not enough? Ideas pls... Sorry for the late. I just made my PC get CVS tree:-( CVS hasn't supported proxy. It brings me some troubles more or less. Thanks for all your concern, Sam CHANGELOG: * Patch by Sam Song, 19 June 2005: - Adjust echo as a defalut command.

[U-Boot-Users] Patch to cpu/mpc8260/speed.c

Hi; I am using u-boot-1.1.2 and I am sending this minor patch to the cpu/mpc8260/speed.c file in view of MPC8280EC document which lays down how the PCIDF is calculated but not reflected correctly in the file.

[U-Boot-Users] Patch to fix jffs2's lack of "data crc".
by Rick Bronson 12 Mar '06

12 Mar '06

1. A description of the bug: When jffs2 reads files it crc's the header but not the data. If the data is corrupt it can cause jffs2 to accept a chunk when it shouldn't. My patch adds in code to crc the data. 2. A CHANGELOG entry Add crc of data to jffs2 (in jffs2_1pass_build_lists()).

[U-Boot-Users] parser problem?
by Andrew Dyer 12 Mar '06

12 Mar '06

I noticed on my board that if I enter a space and then return at the u-boot command line I get an exception. I using u-boot from cvs and the standard (not hush) parser on a mips platform. Does anybody else see this behaviour? -- Hardware, n.: The parts of a computer system that can be kicked.
