I've found that the problem is because uec_phy.c defined these gigabit related definitions since they might be ported from Linux kernel. The redifinition in uec_phy.c should be removed, however I can send the patch for fixing this but I need to get a proper ppc cross-compiler. I will check these stuff after I found and download the ppc cross compiler. Just send a note to mailist. Best regards, Macpaul Lin

Re: [U-Boot] USB storage performance EHCI question - ext2fs performance
by Aaron Williams 21 Jan '11

21 Jan '11

I now have some more information on the performance issue. It appears to be filesystem related. If I format the drive as FAT32 I am getting a transfer rate of approximately 10MB/second. However, if I format it as ext3 I am seeing a transfer rate of only 101KB/second! The only difference is the filesystem and both are clean filesystems. I formatted the drive with: mkfs.ext3 -j -L iomega -O dir_index,has_journal,large_file -t ext3 -v /dev/sdc1 mke2fs 1.41.11 (14-Mar-2010) fs_types for mke2fs.conf resolution: 'ext3', 'default' Calling BLKDISCARD from 0 to 1014095872 failed.

[U-Boot] [PATCH 1/1] DaVinci: Fix DM365 & DM644X build error
by Mohammed Afzal 21 Jan '11

21 Jan '11

DM365 & DM644X builds 'davinci_emac_mii_mode_sel()', which uses 'davinci_syscfg_regs' macro, and the macro is valid iff CONFIG_SOC_DA8XX is defined.

[U-Boot] [PATCH] arm1136: timer: Replace bss variable by gd
by Heiko Schocher 20 Jan '11

20 Jan '11

Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss values in the arm1136 timer driver for mx31 and omap24xx The usage of bss values in drivers before initialisation of bss is forbidden. In that special case some data in .rel.dyn gets corrupted.

[U-Boot] U-boot Config Parameters on Compact Flash
by Dach Miroslaw 20 Jan '11

20 Jan '11

Dear U-Boot Users, I am using successfully U-boot for many years. So far I was dealing with the system which has the Flash memory on board. The u-boot binary and u-boot config parameters were stored in Flash. Currently I am dealing with the new board which has Xilinx Virtex05 chip (with built in powerPC) and Compact Flash instead of Flash memory chip. Compact Flash is interfaced with the system by means of System ACE "interface". Compact Flash has few partitions (ie. FAT and EXT2). Is it possible to configure u-boot to access (ie. read/write) u-boot parameters which are on Compact Flash as a file? I will be grateful for any hint Best Regards Miroslaw Dach
