r8188eu firmware fail from piCore5.2a1 to Core5.2.1?
« on: March 17, 2014, 08:48:17 PM »
I have an existing piCore5.2alpha1 image that is able to boot the TP-Link WN725n (Realtek r8188eu firmware) USB NIC.

I'm not sure the meaning of the last line as the NIC is able to associate and work properly.

In trying to bring up the NIC in Core5.2.1 the firmware fails to load.

Was there a change in the firmware between releases that is causing a failure for the firmware to load?  It appears that the size of r8188eu was 794215 for piCore5.2a1 and shrunk to 780504 in Core5.2.1. Any information would be most appreciated.

It is a staging (experimental) driver which may work or may not. Different size indicates change in the kernel. It is no related to piCore but the Kernel.

Hi, Im also getting a lot questions from piCorePlayer user regarding this wifi - it is not working for them with the new version.

I have seen in the raspberry forum that this wifi adaptor is poorly supported, and a user MREngmann http://www.raspberrypi.org/phpBB3/viewtopic.php?p=462982#p462982 is providing help. It seems like it is dependent upon a firmware file also - the file rtl8188eufw.bin.

Unfortunately, I'm away from my computer the next days, so I can't check if this firmware is included in the new piCore?

Thanks to both for your replies.  At least it confirms I'm not imagining things.

@Steen - the working image is from an older piCorePlayer release.  I will continue to use this as one of my players as I reconstruct my music system.  I have two different adapters in other players working with latest now (EDIMAX and ASUS N10).  As new piCore releases evolve, I can test against the TP-Link and report back.  Unfortunate that the vendor support is not better.  These seem to be readily available and most economical (<$10US) in my area.

Is firmware-rtlwifi.tcz installed?

In the last four month there was only one change in the driver source, an ID change. We can revert this change to see wheher it is the problem or not.

I can confirm exactly the same problem. By going back to the older kernel version 3.12.9, the TP-Link WN725N v2 (r8188eu) works perfectly for me again. However, it would be very nice to get it to work in the present kernel also.

Rebuilt rtl8088eu driver from 3.12.9 source, wireless-3.13.6-piCore+.tcz updated in repo. All other items unchanged. Please try.

Great, thank you for swift action and good feedback on this problem. Now only looking forward to Steen hopefully being able to resolve this problem in forthcoming versions of piCorePlayer ;-)

If you have the WN725 and would like to help verify the driver fix before the next piCorePlayer release, you can try the following with the existing 1.14 image: 
1) Connect your player to the router directly with wired Ethernet
2) Boot and log in via SSH (or your preference)
3) Remove the existing wifi extension
Code: [Select]
tc@piCorePlayer:~$ tce-audit builddb
Building Extension Database from /etc/sysconfig/tcedir/optional
................................
tc@piCorePlayer:~$ tce-audit delete wifi
/etc/sysconfig/tcedir/optional/wifi.tcz

/etc/sysconfig/tcedir/optional/wpa_supplicant.tcz
/etc/sysconfig/tcedir/optional/openssl-1.0.0.tcz
/etc/sysconfig/tcedir/optional/libnl.tcz
tc@piCorePlayer:~$ sudo reboot
4) reboot
5) SSH back in
6) install the wifi extension
Code: [Select]
tc@piCorePlayer:~$ tce-load -wi wifi.tcz
wireless_tools.tcz.dep OK
wpa_supplicant.tcz.dep OK

Just came home and tested on my equipment. Now it works perfectly for me, too with my modified piCorePlayer 1.14, listening to nice music as I write this. Thank you very much to Bela Markus for rebuilding and uploading the driver, and to mcdudeabides for giving detailed instructions on how to get the new version installed.
