Does not work. Output:
| Code: |
sda: unknown partition table
|
It is not clear: the old kernel detects the partition table, but the new kernel does not. |

Something else is wrong: pcmciautils says the card has 16GB, but with pata_pcmcia it says 8MB.
Please post full dmesg outputs of the working and non-working kernels, maybe we can find
some clues in there. |

Full dmesg output of the working kernel:http://pastebin.com/download.php?i=pJ5CNKQ8
But dmesg output of the new kernel is missing, because can not mount root. The output of the new kernel written in my above comments I wrote from the screen hx4700.
In real card has 16GB. |

the old kernel for the hx4700, is that a "vanilla" source or has machine support been patched in?
I get the distinct impression that the pcmcia bridge is missing some customization for the hx4700 in 3.3
Either that or a sublte bug has sneaked into pxa2xx pcmcia support in the meantime. I suspect that
hx4700 pcmcia is missing since the magician_defconfig in 3.3 doesn't enable pcmcia at all |

About old kernel are only known binary and config 
It is a pity that so many in the kernel code for the hx4700, but it can not be used because of this error.
PS On hx4700 now portage offers kernel 3.1.10-gentoo-r1. |

hx4700 PCMCIA support was added to linux-3.5-rc1.
I have uploaded a working hx4700 kernel config for linux 3.5.0-rc2 here:
http://pastebin.com/qcCHkjYL
Note that I use UBIFS instead of JFFS2 for the internal flash (MTD) file systems, so you may need to disable CONFIG_UBIFS_FS and enable CONFIG_JFFS2_FS instead. |

I tried to Kernel-3.5.0-r2 - kernel not started.
On the Kernel-3.5.0-r4 with the proposed kernel config is also not started, but I used magician_defconfig, adding support pcmcia and ata. And the kernel booted, CF-card is determined.
Thank you. |

It is possible that my 3.5.0-rc2 kernel config did not start because of the combination of bootloader and kernel command line.
If you use the SDG bootloader and store Linux file systems in the internal flash (MTD) partitions, then you might need to modify the kernel command line to provide the correct MTD partition information.
For example, I use a modified SDG bootloader to provide the following kernel command line:
| Code: | | mtdparts=physmap-flash:0x00040000@0x00000000(bootldr)ro,0x00040000@0x00040000(sdg),0x00240000@0x00080000(kernel),0x07D00000@0x002C0000(ubi),0x00040000@0x07FC0000(asset) ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs ro |
The MTD partition information is documented in drivers/mtd/cmdlinepart.c:
| Code: | * The format for the command line is as follows:
*
* mtdparts=<mtddef>[;<mtddef]
* <mtddef> := <mtd-id>:<partdef>[,<partdef>]
* where <mtd-id> is the name from the "cat /proc/mtd" command
* <partdef> := <size>[@offset][<name>][ro][lk]
* <mtd-id> := unique name used in mapping driver/device (mtd->name)
* <size> := standard linux memsize OR "-" to denote all remaining space
* <name> := '(' NAME ')' |
The mtd-id provided by the default SDG bootloader is "ipaq", whereas the mtd-id expected by the Linux kernel is "physmap-flash". Therefore if the default SDG bootloader is being used, the kernel will not correctly parse the MTD partition information on the command line, and consequently it will not find the MTD partitions (including the root file system). This can be verified by enabling CONFIG_VT_CONSOLE in the kernel config to display console output on the screen at boot time.
An alternative to modifying the SDG bootloader is to override the kernel command line by setting CONFIG_CMDLINE in the kernel config.
If you use the HaRET bootloader and do not store Linux file systems in the MTD partitions, then perhaps the above problem is irrelevant.
Anyway, it is good to hear that you have CF working! |
