76  Hardware and U-Boot firmware / Hardware / Re: BUG > Bluetooth PAN on Guruplug on: June 25, 2010, 03:23:35 PM

in my Guruplug server +, these 2 files sd8688.bin and sd8688_helper.bin are by default in the directory /root/firmware.
I don't use bluetooth but perhaps these files should be moved into the directory /lib/firmware.
Yes, someone has decided to put those files in /root/firmware to prevent the kernel from finding them. And then that someone decided to do all those messy things with rmmod/insmod in /root/init_setup.sh in the attempt to deal with the "one chip + two firmware + three drivers" situation. The whole thing is one big kludge. Linux is flexible enough to solve those issues in a more decent way, but that is off-topic here.

My point is that, yes, in general the firmware belongs in /lib/firmware, but if you just move it there you may run into trouble because /root/init_setup.sh is not expecting that.

Jun 24 15:28:10 sheevaplug-debian kernel: btmrvl_sdio mmc0:0001:2: firmware: requesting sd8688_helper.bin
Jun 24 15:28:10 sheevaplug-debian kernel: btmrvl_sdio_download_helper: request_firmware(helper) failed, error code = -2
Jun 24 15:28:10 sheevaplug-debian kernel: btmrvl_sdio_download_fw: Failed to download helper!
Jun 24 15:28:10 sheevaplug-debian kernel: btmrvl_sdio_probe: Downloading firmware failed!

In the folder /lib/firmware/mrvl : i have helper_sd.bin  sd8688_ap.bin  sd8688.bin  sd8688_helper.bin
What does mean the error code 2 ?

The error code 2 is ENOENT, which in this context means "file not found".

If you read the error message carefully, especially the part "requesting sd8688_helper.bin", you may notice that it wasn't requesting "mrvl/sd8688_helper.bin". The files "sd8688.bin" and "sd8688_helper.bin" should not be inside "mrvl", they should be directly in "/lib/firmware".

P.S. By the way, don't know if anyone noticed, the files "helper_sd.bin" and "sd8688_helper.bin" are exactly the same, so one of them can be replaced with a link to the other.

The new V2 version due in July has the following redesigned parts:
  • A new inductor on the motherboard
  • A new daughterboard with a new power management chip
  • More vents on the units
  • A new external power supply unit
Where does this information come from?
I can see that the list of the things Globalscale is allegedly redesigning keeps growing. Has any of it been confirmed by them in any form? Or is it just our wishful thinking?

U-Boot can read directly from the nand. But it does not know about jffs2/ubifs.

Actually, u-boot does know about jffs2/ubifs. It can load kernel from inside jffs2 just fine. I haven't tried ubifs though.
As far as I can tell by looking at the u-boot sources, there is some code to deal with ubifs, but I don't know what exactly it can do and how complete it is.

Oh by the way there was a recent check in to u-boot for a fix to the way u-boot does reset of PHY chip.  It was not resetting it correctly.
Could you provide a link to that information? I suppose there are many people who would like to try that too.

If you don't need Wi-Fi or BlueTooth or dual Ethernet, but do need a lot of storage, you might consider bying one of Synology NAS. I have got DS-210j, which has exactly the same CPU as GuruPlug. Just like SheevaPlug/GuruPlug, it is open for customizations and Synology provides the toolchain to cross-compile applications to your taste, although you don't get JTAG or access to whatever boot loader it uses (not directly in any case). And most of the features you need you will get out of the box.
