[U-Boot-Users] KK trizeps2

Hi, I have trizeps2 board from keith&koep with pxa255, 16Mb flash and 64Mb ram. It also comes with their bootloader, but I would like to have u-boot running on this board. I don't have BDI or similar debugger yet, so I can't do any serious work in porting it myself. Has anyone succeded in porting u-boot to this board? At least the early initialisation part... thanx, h -- hinko <dot> kocevar <at> iskramedical <dot> si Hinko Kocevar, developer Iskra Medical d.o.o., Stegne 23, 1k LJ, SLO-EU "Aì rén" | [Analects XII:22]

[U-Boot-Users] Who sets the boot parameters?
by Shawn 19 Nov '04

19 Nov '04

Hi, The boot parameter is transferred to a linux kernel by r2. Many boards set the bd->bi_boot_param to a fixed address? How does this value come from? Who set the boot parameters at that address? Thanks, -Shawn.

[U-Boot-Users] Sharing Question....
by Robin Getz 18 Nov '04

18 Nov '04

On my board, I share the same memory space for flash, as I do for ethernet. (my processor only allows 4Meg of external async memory, in 1Meg address size, and I have 4 Meg of Flash). Today, I swap things over in the ethernet driver (a small ifdef <board_name> in eth_start and eth_end). Since this is in the architecture independent code, I know this is a no-no... Is there a better place to put things? I tried in the flash.c but that means when I want to do a memory dump, I always see ethernet, not flash, and after a cp.b, a cmp.b doesn't work. Thanks -Robin

No patch includes HRCW configurations unless you (or someone else) provides it to Wolfgang. U-boot is self-serv[e|ing] ;-). Having said that, I will put it into my build and roll another patch for Wolfgang, superseding my previous patch. I neglected to update the README to discuss the added _lowboot configurations which has been bothering my conscience, so I need to add that too. Per your previous email on the flash width/HRCW/BPS, that was my bad on the BPS field.

[U-Boot-Users] mpc8272ads lowboot ... I got it

Hi all, Wooouh, this morning I was sleeping. I have post the mail to the wrong list and with the wrong Subject (sorry to those in the linuxppc-embedded list). Well, I finally got uboot-lowboot working. The problem was in the CS6PC bits (24-25) in the HRCW (i think these are the same than CS10PC bits in the PQ2ADS). This must be configured as CS6 (00), not as BCTL1 (01). So, the HRCW for lowboot in the MPC8272ADS i have used is 0x0E_74_B2_0A. Now it works great. Thanks Gerald. Will the patch finally include the different HRCWs? At least, this should be documented, shouldn't it? Alex

The board is arm920t based and it's UART port is compatible with ns16550.c so I changed the serial driver (serial.c) on the cpu/arm920t directory with the serial driver + ns16650 module available in the drivers directory. I am using bdi2k for debugging and I have initialized the UART port on the bdi2k config. The problem is that when the initialization routine in armboot_start calls serial_init of the ns16550, there are no messages, i.e. no prompt, on my serial console. When I remove the serial_init on the list of initialization functions of armboot_start, a prompt appears. I can successfully type help, and do other stuff. Whenever I try to remove the initialization routine on my BDI2k configuration and put back the serial_init function on the initialization list, I am not getting any messages on my serial console. What could be the cause of this problem? The initialization routine on the bdi2k and serial_init are almost the same (i tried to make the sequence and the values exactly the same but I get the same result) but there are no messages displayed on my console. =( Thank you very much for your help.

I used an SDRAM driver which works normally in VxWorks. But when I call the relocate_code() funtion, there is an error of byte ordinary. If I write a number to memory, the higher 16 bits exchange position with lower 16 bits. For an example, if I write 0x2705,1956 to sdram, then I get 0x1956,2705 when I read the memory address. But I can read or write flash correctly. I read chapter 13.2.3 of the guild file.

[U-Boot-Users] FEC problem on mpc852T
by Carl Yang 18 Nov '04

18 Nov '04

Hi, I am having some problems getting the FEC to work, perhaps someone on the list has seen something like it and can help me out? In my setup, I connected my board directly to a host via crossover Ethernet cable. From the serial console connected to my board, I typed "ping 172.10.18.59." On the host, I ran Ethereal and I can see my ARP request packet and also the host responded. I think as soon as the ARP response packet is recieved by FEC, the serial console locked up and on my telnet bdi session, I can see that there is a machine check failure. From the telnet bdi session, I then checked out the I_EVENT register and I saw that the EBERR bit is set (Ethernet bus error occured. Indicates that a bus error occured when the FEC wss accessing the U-bus. By the way, this is on u-boot 1.1.1. Regards, Carl Yang __________________________________ Do you Yahoo!?
