CM-x2xx. The PCI implementation in Linux kernel for ARM architecture does not set up latency timer for the PCI masters. This timer setting is required for fast PCI devices behind the ITE8152 bridge.

There're two possible solutions to this problem. The first, is to use setpci utility. Using this utility one can modify the latency timer of the PCI device:

# setpci -s <bus>:<slot> 0d.B=40

The other way is to modify Linux kernel PCI code, so that it will setup PCI masters latency timers, as for example done in pcibios_set_master in arch/i386/pci/i386.c

Recently we get a lot of complains about incompatibility between Scratchbox toolkits and our Debian Linux for CM-x2xx. Indeed, Scratchbox latest release, called Apophis contains EABI toolchain, which is not supported by current stable Debian ARM Linux. Yet, the Scratchbox release 0.9.8 (marked legacy), is fully binary compatible with Debian ARM Linux for CM-X270. So, if you'd like to take advantage of Scratchbox flexibility and Debian huge package base at the same time, please use Scratchbox 0.9.8.

CM-X270. Since ARMmon released on 16-Aug-2006, kernel image in NOR flash is prefixed by the image size. If you use UsbMLink for downloading kernel image to the CM-X270 NOR flash, you should also use nor_prefix.exe that adds this prefix to the image. The nor_prefix.exe adds a 4 byte file length prefix to kernel image, required by new bootloader. (Note: use nor_prefix only for installation by UsbMlink). For help run nor_prefix.exe without arguments.

12-Oct-2006

Released new kernel for CM-X270 with various minor fixes. The Debian image for CM-x2xx is also updated with latest kernel modules.

05-Oct-2006

Fixed month read bug in the MAX6902 RTC driver for CM-X255. Line 98 of drivers/char/max6902.c instead of

       dt->tm_mon = BCD_TO_BIN(max6902_get_reg(0x09)-1);

should be

       dt->tm_mon = BCD_TO_BIN(max6902_get_reg(0x09))-1;

05-Sep-2006

Added preliminary release of Linux packages for CM-iGLX. It can be downloaded here. This release includes Linux kernel 2.6.17 optimized for AMD Geode LX800 processor and CM-iGLX borad. There are also Debian linux images customized to run on CM-iGLX with 128 or 512 MByte on-board NAND flash storage.
