uio driver cannot be registered to uio subsystem

the uio drivers which are provided by the kernel itself. But after starting the kernel not one of these drivers appears in /sys/class/ too! Can anybody please tell what I am doing wrong? Pls see below, too! Thanks in advance! Kind regrads Frank Prepelica Software Design Engineer Ubidyne GmbH Lise

AW: How to set DDR data bus width to 16Bit

you have to do it via your bootloader (u-boot) which sets up the DDR memory controller. Linux (already) assumes memory is available. Are you sure linux kernel is changing DDR_SDRAM_CFG ? When our linux-2.6.28 kernel is up, it's still 0xc308 when I read physical address 0xe0002110. Hi

tree. Hmm, but I do have a PHY, don't I?. The PHY will be emulated in the FPGA. Of course, it's not a physical PHY but it should look like one. So, do I really need the remove the complete PHY description in the DTB? Frank Prepelica Software Design Engineer Ubidyne

connection between and MPC and a Virtex FPGA. Whats about the PHY address which has to be set in the DTB file? Do I have to modify the DTB at all? Thank you! Best regards Frank Frank Prepelica Software Design Engineer Ubidyne GmbH Lise-Meitner-Str.-14 89081 Ulm

How to set external interrupts falling edge sensitive

Hi all, I'm using the mpc8313erdb. I got two external interrupt sources which are handled by two UIO drivers. These interrupts shall be triggered on falling edge. Therefore I just added (Kernel version 2.6.24) in arch/powerpc/sysdev/ipic.c in function ipic_set_irq_type at line ~484 flow_type =
