[U-Boot-Users] U boot modification...
by Kiran Jammula 23 May '12

23 May '12

Hi, I am using U boot for my project. I need to configure the console while booting by prompting the user from target board LCD and Keypad. So please let me know which file of the U-boot I have to modify to achieve this.

[U-Boot-Users] Ethernet loopback command
by Thomas Schäfer 17 Apr '12

17 Apr '12

Hi, The patch attached provides a command called 'ethloop' which allows to perform loopback testing on the current eth device. To achieve this, a new ethernet packet type (PROT_TEST, 0x0808, AFAIK this is not used otherwise) is introduced in net/net.c. The patch is against SF CVS from 20050307. The functions EthLoopStart, EthLoopSend and EthLoopHandler generate a simple ethernet frame with NetOurEther as destination address and packet type PROT_TEST. The looped back package is compared with the original one and a message is displayed. It is necessary to set the ethernet line into loopback mode either by programming the PHY or using a loopback plug. I've tested this on our PPC405 custom board, but it should also work on all other systems because packet generation is independent of the underlying ethernet hardware. Example usage: => mii w 0 0 7100 <-- sets PHY into loopback mode => ethloop Using ppc_405x_eth0 device Got ethernet loopback frame, len=64 loopback test successfully completed => mii w 0 0 8000 <-- PHY reset after test is completed Maybe this is also useful for others..

[U-Boot-Users] mtdparts
by Ladislav Michl 29 Oct '06

29 Oct '06

Hi there. I'm just trying to sync with U-Boot development and found a little regresion in new mtdparts code. Previously I was using custom partition function, which let me do precisely what I wanted. mtd0 - U-Boot mtd1 - env mtd2 - r_env mtd3 - rootfs0 mtd4 - rootfs1 ... etc In above scheme my custom part function allowed only chpart [34], so it was not even possible to change partition to evn sector for example. Moreover it was pretty easy to construct kernel command line this way: setenv bootargs '$bootargs root=/dev/mtdblock$partition ro rootfstype=jffs2' And everything worked nicely. That is no longer case and it's real pain with both NOR and NAND devices used in system. Prefered solution for me is to fix kernel to be able to mount root filesystem from MTD device given by name (root=mtd:rootfs0) unless someone has better idea :-). Something which would work also with 2.4 kernels would be appreciated. ladis

[U-Boot-Users] New NAND code
by Stefan Roese 10 Aug '06

10 Aug '06

Hi! I was just wondering about state of the NAND code. When I remember correctly a pretty big rewrite was done but not commited yet. Is the last patch sent to this list from Pantelis Antoniou on 5th May still the latest version? Best regards, Stefan

[U-Boot-Users] MIPS: AMD Alchemy au1x00 ethernet problems
by geoff cleary 23 Jul '06

23 Jul '06

Hi I am seeing a problem with network support on the AMD dbau1550 eval board (and our own board based on Au1550). It seems that after one network command, no further packets can be sent. The minimal case that shows the problem is to include the ping command. The first ping will succeed; any other network commands time out. I have successfully loaded large files using tftpboot command and confirmed the image loaded correctly. Trying the command again fails with TX timeout. Has anyone seen this problem or have any suggestions as to what is going on? We are building little endian. I have tried Joseph Chiu's buffer 0 patch. Thanks Geoff __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Sorry the patch below isn't from git - I hope it's still acceptable. I've put a copy in the body and attached it incase gmail decides to line wrap the text.
