Wolfgang,

Your recommendation was well noted but at this point I want to avoid using u-boot image, compiled by myself from the source. At this point I want to use the "tried"/"tested" bootloader In my opinion, my question re usability of the u-boot bootloader images provided on the Arabella 2.0 CD-ROM "Linux for Motorola 82xx" is still worth to be asked/answered - this cdrom is "packaged" by the Freescale, when they ship the brand new board. Also FreeScale "packages" Code Warrior 8.14 (with one month evaluation license) + WireTAP probe into the shipment.

Do you yourself have the PQ2FADS_VR 66 MHz board (with the MPC8275 processor) by any chance (as well as Arabella 2.0 CD-ROM "Linux for Motorola 82xx" ?) ?

Thanks Alex,

Did any one on this list used elf bootloader for PQ2FADS_VR 66 MHz board (with the MPC8275 processor) provided on the Arabella 2.0 CD-ROM "Linux for Motorola 82xx" ?

I already replied to your question on the etux mailing list. There was no need to repost the very same question here. My hinto to post on u-boot-users was intended for _new_ questions.

...

While the programming of the flash seemingly completed without errors - however the resulted bootloader is not functional ... -

I repeat my recommendation:

Use the latest version of U-Boot (top of CVS tree). See http://sourceforge.net/projects/u-boot and http://www.denx.de/twiki/bin/view/DULG/Manual

Best regards,

I'm not answering the questions that were asked, but I figured a testimonial wouldn't hurt:

My configuration: * PQ2FADS-ZU with a MPC8260 * BDI2000, MPC8280 configuration downloaded from denx.de * Remaps the IMMR from 0x0F000000 to 0xF0000000 * Initializes SDRAM * U-boot build top of the u-boot CVS tree (synced the week of 2004-09-12, I don't remember the exact date).

I had to change the BDI2000 JTAG clocking to 8MHz (JTAGCLOCK 1) from the default 16MHz (JTAGCLOCK 0) before the flash would program reliably. With the 16MHz clock it would only program 1K+ and then have an error.

The board is booting with the (default) BCSR-supplied HRCW ((IMMR = 0x0F000000) == yech). I cannot boot it with the BDI2000 plugged in, probably due to the HRCW. If the BDI2000 is plugged in, u-boot starts to run and then the BDI2000 gets unhappy and resets the board.

ToDo: * Change the J7 jumper to use flash for the HRCW * Reconfigure u-boot to boot low (preferred configuration) * Reconfigure the BDI2000 to... * Not move the IMMR (not necessary or desired with a flash HRCW) * Remove the SDRAM initialization (SDRAM init is poor practice) * Get ethernet configured and running... * Boot linux!
