I was trying to load linux-2.4.4 in FADS860T board using u-boot-1.0.0. I have settted environment variables like ipaddr,serverip,ethaddr,bootargs bootfile and saved the environment. Then,i typed tftpboot to download image from server. Then,i typed bootm to start the booting process. System is stucked by showing "Uncompressing Kernel Image ... OK" sequence of these events r given below.can u please suggest, what i need to do to come out from this. Thank you.

[U-Boot-Users] Patch: MPC8xx interrupt
by Pierre AUBERT 06 Dec '02

06 Dec '02

Dear Wolfgang, Currently, for the MPC8xx cpu, the irq_install_handler/irq_free_handler works only for the CPM interrupt. The attached patch allows to use irq_install_handler and irq_free_handler for external interrupts _and_ CPM interrupts. Best regards CHANGELOG: * Patch by Pierre Aubert , 28 Nov 2002 Add support for external interrupts on MPC8xx

[U-Boot-Users] PPC: problem with syscalls
by Pierre AUBERT 06 Dec '02

06 Dec '02

Hello everybody, I've a problem with examples/timer.c. I've tried to launch it on my mpc860t board, if I start the timer and if I press a key after one or more interrupts occured, the u-boot crashes. The problem is that an interrupt handler uses a system call (mon_printf) while the main loop is inside a system call (mon_getc). During a system call, the LR and SRRx are saved at a fixed location (0xcf4, 0xcf8 and 0xcfc) then the return address of the mon_printf in the main loop is overridden by the return address of the mon_getc in the interrupt handler. To avoid this problem, I think that we need to use a stack to store the return addresses (and the SRRx) of the system calls. What's your opinion ? Best regards

[U-Boot-Users] RE: [PPCBoot-users] How to load Linux locally?
by Joe Hamman 26 Nov '02

26 Nov '02

Hi Francis, The best way to debug this is to set an internal hardware breakpoint at address 0. Use the terminal window command IHBD 0. It's easier than using the GUI. Start the target running and let UBoot load the kernel. When it jumps to location 0, you'll hit the breakpoint and be able to step through the code. The MMU is turned on very shortly (15-20 lines into the code), so you'll need to have the visionICE II configured with the CF MMU commands or it will get lost once translation is turned on.

Joe, I cannot thank you enough for the following step-by-step instructions that you have listed so clearly. It works! I am so happy to observe that the PPCBOOT decompressed the kernel image at the location that I have downloaded and see the message "## Transferring control to Linux (at address 00000000) ...". But soon it died inside "InstructionTLBMiss". This would be a question not belonging here... Any way, as Wolfgang has been repeatedly stating "RTFM!!!". I guess I am simply overwhelmed with so much information out there that sometimes it is difficult to sift through them all to get the right answer. Once again, thanks to all you folks.

Hi Francis, If you cannot use ethernet, do it this way: Put the linux build environment back to its original form. Make pImage - this generates the file zImage, packaged with the mkimage utility. PPCboot knows this format. If the kernel distribution you are using does not support this, get one that does. Convert pImage to a .bdx file using visionCLICK. Go into the project configuration, go to the Load Options tab, and set the Apply +/- Bias to something like 100000. Don't forget to check the box to enable the bias. Save and exit the project configuartion dialog. Reboot the board (INN;GO <RETURN> at the BKM> prompt). Stop the PPCboot autoloader (if it is enabled) and get to the PPCboot prompt. In visionCLICK, stop the target (click on the stop sign icon or type 'ha' or 'halt' at the RUN> prompt). Then use the 'File | Load A Target Image' pulldown in visionCLICK to load the pImage.bdx. Start PPCboot running from where it left off (click on the green light icon or type 'go' at the BKM> prompt). At the PPCboot prompt, type 'imi 0x100000' to see if it recognizes the image you just loaded into ram. If recognized, use the 'bootm 0x100000' command to have PPCboot uncompress and launch the image. Don't forget to read all the docs on www.denx.de. Good luck!

Hi! After spending some time to modified the files for my custom PPC board, I finally got the ppcboot up and running ( to some degree). I programmed the ppcboot in flash at 0xfff0,0000, and after resetting the board the ppcboot will tell me that I have 16M DRAM starting at 0 to 0x00ff,ffff, and the ppcboot has relocated itself to 0x00fc,0000. If I hit any key at this time it stops the boot request and gets into the command mode, waiting for the user input. My next step is to try to load Linux locally without using FTP. I have built the vmlinux.srec and convert it into the bin format using the VisionClick ( yes, I do not have the BDI2100 but believe me I would have gotten one if the darn economy is not this bad!) The original address is linked at 0xc000,0000, but since I do not have any memory there I tried to build the vmlinux by modifying the KERNELLOAD to be 0x0080,0000, then loaded it to RAM using the VisionProbe. I then use the GO command of the ppcboot to jump to 0x0080,0000. As expected, it crashed. 1/ Is the Linux kernel always linked at 0xC000,0000? What if I do not have any memory there? 2/ In reading section 6 of the PPCBOOT's document, "Booting Embedded Linux", is the embedded Linux in this case means the compressed Linux kernel plus the bootstrap and decompressor, otherwise known as the Zimage or Pimage? 3/ I tried to use the bootm command to boot the "embedded kernel", (I guess it would be the zimage which I have loaded into RAM at location 0x0040,0000) but it returned with the "Bad Magic Number" message. How do I build the zimage so that I could pass this stage? I know that I am testing your patience with my stupid questions, which seems so obvious to most of you, but for a guy who is new in this area, please bear with me.

[U-Boot-Users] PATCH: Driver for the Epson SED13806 graphic controler
by Pierre AUBERT 25 Nov '02

25 Nov '02

Hello everybody, Please find attached a patch that add support for the Epson SED13806 graphic controller. This controller is used on the Embedded Planet ECCX daughter board. Please see the RPXClassic.h file for the details of the configuration. This patch also adds the support of the BMP logo in cfb_console driver. >From now, the cfb_console driver was only able to display the logo included in the file logo_linux.h. The MPC8xx LCD driver use the logo included in bmp_logo.h. This file is very easy to create because the tool bmp_logo is included in U-boot. I saw that the video driver for the MPC8xx use another logo created by easy_logo. I think that it would be nie to use only one file format in all the graphic drivers. To use the BMP logo with the cfb_console driver, add #define CONFIG_VIDEO_BMP_LOGO in the board config file (see RPXClassic.h). This patch fixes also a warning in mkimage.c. CHANGELOG: * Patch by Pierre Aubert , 20 Nov 2002 Add driver for Epson SED13806 graphic controller. Add support for BMP logos in cfb_console driver. Best regards
