Re: [U-Boot-Users] PQ2FADS-ZU PQ28280 access to 60x bus SDRAM failed when localbus is in PCI mode?

Hi; I have managed to boot up the board into PCI mode after looking at the various clock configuration modes laid down in MPC8280EC document. However, I have tried with some values but I can't get PCI to run at 66.7 MHz. In addition, the PCIDF read from SCCR does not seem to match the values laid down in the document with the MODCK values configured at SW6. Please advise if anyone has managed to get the PCI interface of PQ2FADS-ZU to run at 66.7 MHz.

Such a configuration works OK for me. There are some things to check. You don't write what HRCW you use: from BCSR or from flash. If the latter, you have to change pin assignment bits and MODCKH accordingly. Also, clocks are calculated differently in PCI and local bus modes. Check the MODCK/MODCKH values (SW6). Valid local bus mode values can be invalid in PCI mode. -- ======================================================================== Yuli Barcohen | Phone +972-9-765-1788 | Software Project Leader yuli(a)arabellasw.com | Fax +972-9-765-7494 | Arabella Software, Israel ========================================================================

[U-Boot-Users] PATCH: arm gcc options && GCC version for Linux kernel?
by Peter Pearse 15 Jun '05

15 Jun '05

Hi ARM board users may be interested in the attached patch which patches mkconfig to detect which arm specific options are available & converts gcc calls in all config.mk files accordingly. It has been running happily with my nightly MAKEALL arm on the U-Boot CVS head for a couple of months. ------------------------- Peter.Pearse(a)arm.com ------------------------

Hi all, My configuration is a U-Boot-1.1.2 working on MPC8280 based Rattler board. When I am trying to run Watchdog test on the card, it fails always. In the config file. Rattler.h, I have the following related to watchdog: #define CONFIG_WATCHDOG #define CONFIG_POST (CFG_POST_CPU | \ CFG_POST_WATCHDOG ) Is there anything else that is missed out? Thanks for all the help provided. With Regards, C.R.Srivatsan

[U-Boot-Users] GCC version for Linux kernel?
by Allen Curtis 15 Jun '05

I am using GCC 3.4.2 for PowerPC. When you compile the Linux 2.4 PPC kernel you get lots of "deprecated" warning messages from the compiler. What is the recommended GCC version? TIA

Because 826x doesn't use upm for SDRAM.

Make sure U-Boot doesn't try to initialize the SDRAM on the localbus.

[U-Boot-Users] U-Boot Support for EP885C
by Will Haines 15 Jun '05

15 Jun '05

I am new to U-Boot, and I was wondering if anyone here knows of U-Boot support for the Embedded Planet EP885C board. I don't yet have the knowledge required to port the bootloader, but I know that my board is similar to some that U-Boot already supports. If anyone knows of a way to get U-Boot running on the EP885C, I would greatly appreciate some pointers. Much Thanks, Will Haines
