I'm trying to use my Dreamplug as AP. It's a 1001-model, with a SD8787. I downloaded the kernel 3.12.1 from 'xilka.com' and even got a new uInitrd going. I also downloaded the file sd8787_uapsta.bin and put it in /lib/firmware/mrvl.

I get the card to run in client mode, but I never see a uap0 device, only mlan0. What else must I do to be able to use the wifi as AP?

In case someone else has the same problem, reinstalling Debian on an SD card solved the issue:

After replacing the blown PSU with a new one from NewIT, the Debian6 that I use to upgrade from the original Ubuntu 9.04 no longer boots.

I'm no Linux expert, and have no idea what to try.

Thanks for any help.

Here's the output from the micro-USB port as seen by Putty in Windows:

Hi all,

I have here a Guruplug that doesn't boot any more. With the help of the JTAG-debugger, I have figured out that the processor doesn't jump to the U-Boot start address 0x00600000. Furthermore, it remains in an endless loop at address 0xffff0b2e:

> halt
target state: halted
target halted in Thumb state due to debug-request, current mode: Supervisor
cpsr: 0x400000f3 pc: 0xffff0b2e

But when I load the U-Boot over an OpenOCD-session and execute 'resume 0x00600000', the bootloader starts as expected. Now, my question: does somebody knows how to solve this problem? Thanks in advance.

I went through the threads on the subject, and since it requires some knowledge of electronics, which I don't have, I just ordered a new PSU from NewIt, although 10 + 10 is a bit high if it just means replacing one or two caps :-/

Thanks for the infos. I attached a picture of my dead SP.

Is there a precise, newbie-accessible HOWTO on what component to order and how to perform the operation, including how to use a multimeter?

Updated u-boot 2013.10 final attached, flash like so:
copy to fat16 usb stick
in existing console:
usb start
fatload usb 0 0x800000 u-boot.kwb
nand erase 0x0 0x80000
nand write 0x0800000 0x0 0x80000

it is very risky
i want to see all console output
so i better stay with previous kernel
kirkwood-* kernels boots without such problem (but lacks uap module)

i don't use 'machid'

Although the console 'freezes' with Device Tree kernels earlier than 3.11.2 for Guruplug (I am running this on my Guruplugs) it is possible that you may get access using SSH after a period for the kernel to boot fully.

Another possibility is do you have a line 'machid=a63' in your u-boot environment? (Replaces arcNumber.)

guruplug freezes after message "Uncompressing Linux... done, booting the kernel."

i use these variables:
arcNumber 2659
mainlineLinux yes
