[U-Boot-Users] common/cmd_mii.c bug and patch
by Andrew Dyer 24 Sep '05

24 Sep '05

The mii info command (the !CONFIG_TERSE_MII version) has a bug in current cvs. If the phy address is passed to the command the code assigns the variable addr to start, instead of the values of addrlo which is extracted from the command line. At that point in the code addr is always 0. to demonstrate find a board with a phy at a non-zero address, compare the results of 'mii info' and mii info 1' (substitute the phy address on the test board for 1). Also in this file on lines 55 and 418 there are two places where a call to mii_init() is conditionally compiled in, but one condition includes defined(CONFIG_MCF52x2) and the other doesn't. Is this intentional? -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] debugging U-boot with GDB on a Au1550
by Cliff Brake 22 Aug '05

22 Aug '05

I have U-boot running on a Au1550 platform. I have verified that re-location to RAM works but the system is crashing somewhere in board_init_r. I would like to debug this with GDB and a BDI2000, but am running into a few issues. U-boot for this platform is linked to 0xbfc00000 (the ROM reset vector). This is not what I am used to as most ARM platforms are linked to the RAM location. After U-boot is relocated to RAM, how do I tell GDB what the new link address is (0x80fdc000 in this case)? Thanks, Cliff -- ======================= Cliff Brake http://bec-systems.com

[U-Boot-Users] PATCH: Add sandburst metrobox board support [2/3]
by Travis B. Sawyer 15 Aug '05

15 Aug '05

[Note: My previous submission was rejected due to size] This patch adds the Sandburst Metrobox and Sandburst Karef Boards. Both are PPC440GX based, direct peripheral bus connected compact flash, dallas rtc, write protected eeprom (strappings and ethernet MAC address). EMAC 2 is the management ethernet interface, EMAC 3 goes to a board to board connector. These boards are reference designs for the Sandburst HiBEAM chipset. See http://www.sandburst.com for more board information (predominately marketing speak). This patch is against source forge cvs 12July2005, at approximately 0900 EDT. CHANGELOG: * Patch by Travis B. Sawyer, 12 Jul 2005: Add Sandburst Metrobox and Sandburst Karef board support packages. Second serial port on 440GX now defined as a system device. Add 'Short Etch' code for Cicada PHY within 440gx_enet.c Best regards, Travis Sawyer

[U-Boot-Users] Building u-boot for Ocotea fails...
by Gerhard Jaeger 15 Aug '05

15 Aug '05

Hi, while trying to build a u-boot image for Ocotea out of the latest CVS, I noticed the following problem: ppc_4xx-ld: section .bss [fffeeb00 -> fffffec7] overlaps section .bootpg [fffff000 -> fffff21b] This one should be solved, either by reducing the command set (i.e. removing CFG_CMD_BEDBUG) or increasing the size back to 512k, as it was before the latest changes took place...
