We are using Phytec's i.MX27 board, so we are 'stuck' with that version. I'm sorry if this questions has been asked before, but do you see more momentum to push for V2? It's probably too early to ask for a separate V2 mailing list? > folks on the list have been bashing my head with it ;)... happy hacking... Thanks. I'd like to help but unfortunately, I'm just too busy to help out at this point. :-( Cheers! -Chris

[U-Boot-Users] PCI stopped working on MPC8343
by Andre Schwarz 08 Jul '08

08 Jul '08

Last week my PCI bus has been running fine showing all devices. Right now no devices are shown on the bus. I'm using CONFIG_83XX_GENERIC_PCI with common setup code for PCI. Nothing changed from my side during the last 2 weeks. Did I miss any changes in u-boot ? regards, Andre Schwarz Matrix Vision MATRIX VISION GmbH, Talstraße 16, DE-71570 Oppenweiler - Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschäftsführer: Gerhard Thullner, Werner Armingeon, Uwe Furtner

Hi Sascha, You misspelled 'CONFIG' in your last check-in: 7c37b54184893d4fe4e23933e6a8deae1c9d62a2.

[U-Boot-Users] Debugging U-boot using Trace32 in Linux..
by Yi-Neng Lin 08 Jul '08

08 Jul '08

Hi there, Recently I've been trying to debug U-boot using Trace32 in my Fedora Linux. Since the software does not have a linux version, I tried to use WINE, a windows emulator, to execute the binaries. But it just does not work (via parallel port). Can anyone here give me a pointer about this? Did anyone succeeded in debugging with Trace32 in Linux? Thanks a lot. Yi-Neng

[U-Boot-Users] Custodianship updates
by Wolfgang Denk 08 Jul '08

08 Jul '08

Hello everybody, as many of you will have seen, there have been a few areas in U-Boot where processing of patches and new code submissions did not work as quickly and smoothly as we all would have liked. I'm all the more happy to be able to announce updates for two (IMHO both important) areas: * ARM: Peter Pearse has been trying his best to do a good job to maintain the (huge!) ARM part of the U-Boot project, but he did not find enough free resources to do this on a regular base. I know all too well how that feels, as I'm in the very same situation too often myself. But now we have the chance that Jean-Christophe Plagniol-Villard volunteers to help out, and given from the previous activities he has shown on the mailing list I think that he is very capable of doing that job. Peter has agreed that Jean-Christophe takes over the custodianship for ARM. If there are no objections (or better suggestions) I would install this change more or less immediately. Comments? * MPC512x: as it turns out, Grant Likely, the custodian for MPC5xxx systems, finds neither time nor resources to work with MPC512x processors. Fortunately John Rigby volunteered, in addition to all his previous work he has optimal access to recent hardware and documentation :) If there are no objections, I would like to split custodionship for these processors into "MPC5xxx" (meaning actually MPC5200), handled by Grant Likely as before, and into MPC512x, handled by John Rigby. Comments?

[PATCH] add new NAND_DONT_CRATE_BBT flag This patch makes creation of the BBT optional. It adds a new platform-independent NAND-wide flag NAND_DONT_CREATE_BBT This flag can be used by the board_nand_init function of a board.
