unable to locate package ipkg

Upgraded from Ubuntu 10.04LTS to Xubuntu 14.04LTS on both my desktop and
netbook.

I can ptxdist go and ptxdist images on the Desktop but on the netbook,
withptxdist images, I get the following error:

davef <at> davef-AOD255E:~/OSELAS.BSP-Pengutronix-Mini2440-2013.10.0$ ptxdist images

It doesn't seem to make any difference ticking or unticking ipkg in Disk and
File Utilities.  Before I completely re-install ptxdist is there an easier
fix to this problem?

Thank you,
Dave

Stare and compare ... Opus 2


Let's see, Mini6410 and linux-3.14.19.

Thus spoke dmesg:

Well ... <sigh> ... That's less than optimal.

So, where does this error come from?  Let's see ...

   drivers/usb/host/ohci-hcd.c

contained within:

around line 674:

... a time honoured tradition.  No doubt about that.

Friends, Geeks, Hackers, I come not to bury the kernel, but to praise 
it.  The evil that change does, lives after; the good is oft interred 
with its bones.  So let it be with this change.

Enough foolishness.

Foolishly I was hacking on my Mini6410 and despite many hours of trying 
to get the FA '1wire' display to function as a touchscreen; sadly I have 
failed.  Hence, I hit upon the bright (dim?) idea of moving the 6410BSP 
forward to using linux-3.14.19.  Brilliant!  You say?  Hah!  No fool 
like an old fool.  So they say.  Whoever 'they' are.  Get off my lawn! 
Bah!  <grumble>

In the beginning, progress was good, and I was feeling pretty darn 
arrogant about it.  Hah!  Such a fool!

Then this happened:

mini2440 FA 1-wire support (with patches)


Credit where credit is due:

Thank you, very much, to Tomasz Figa for his work on FriendlyARM '1-wire'.

Thank you to Juergen Borleis for his work supporting the Mini 2440.

With a measure of certainty, I'm reasonably confident that I've done 
something incorrectly.  Hence, it would be nice if someone could test 
these patches.

Theory:

It seems (from reading the mailing list) that others would like to have 
this FriendlyARM 1-wire support for both the Mini 2440 and Mini 6410.

Hopefully, it doesn't offend any one that I renamed T. Figa's files 
(which were applied to the 6410 project).  It seemed like they would be 
useful to both the 2440 and 6410 (and probably other) boards; hence, I 
created these patches to be (hopefully) useful to both.

Practice:

I added the following:

   # FA 1-wire Support
   fa_1wire_fa_1wire.diff
   fa_1wire_fa_1wire_ts.diff
   fa_1wire_mach-mini2440.c.diff

If you take a closer look, the "size=1024M" is inside the "image" block. So it 
defines the size of the whole image file to be created.

UART Communication FriendlyARM-mini2440

Hi,

I am facing a strange issue.. in case any one has faced this kind of issue and have any suggestions, please let me know...

if I would like to send and array of 8 bytes such as below through UART such as ttySAC1, ttySAC2 etc,  the byte containing 'zero' is not transmitted.. below is the example...

I have an array of unsigned char alph[] = {'a', 'b', 'c', 'd', 'e', 0x00, 'g', 'h'};
when this is transmitted over UART,  the output would be "abcdegh" only seven characters and the zero is missing... 

in the same way, one more.. try sending unsigned char reset[] = {0x01, 0x06, 0x00, 0x01, 0x00, 0x01, 0x19, 0xCA};

I would only see "01 06 01 01 19 CA"  only 6 bytes.. byte containing zeros are missing again..


in case any one have had this kind of issue and have suggestions, please let me know...


Thanks,
Girish

Sure. That is why the checksum exists: to ensure the archive you are using is
the same than we are using.

Where did you install your PTXdist?

Changing MD5 of QT4

Hello,

Could some one let me know where(which file) can I change the MD5sum of QT4 so that ptxdist does not crib saying that MD5SUM error for QT4.  just like as we give 
"PTXCONF_BAREBOX_MD5="d66774abcf9fa6c9530e13543cc707bc" for barebox in "platformconfig-NAND-128M" file, I would like to set md5sum for QT4

TQMa6x BSP Rev.0104 AHCI configuration

Hello again,

Thanks to all of you for your help so far. I hope you can provide me with some guidance on this AHCI (possibly configuration?) issue.

With Linux TQMa6x BSP Rev.0101, my AHCI device (a Plextor solid state drive) that I had connected to the TQ system was detected. (I show output from various command in the section below labeled "Previous BSP (0101) Version.")

In the newest BSP (Rev. 0104) this same AHCI device is NOT detected. Can you tell if I should expect AHCI to work on Rev 0104 and if so, what changes I must make to get it working?

Here is the result of several commands on the BSP 0104 system (OSELAS(R)-TQC-ARM-BSP-QT-20140718 / MBa6x-20140718 ptxdist-2013.12.0/2014-09-16T16:48:08-0600)       

"uname -a" reports:

Linux MBa6x 3.16.0-rc5-20140718 #4 SMP Wed Sep 10 18:44:53 MDT 2014 armv7l GNU/x

"lspci -m" and "lspci -k" produce no output -- nothing at all.

In /dev, I see no sd* devices.

After installing a BSP 0104 image on the TQ system, these are the files with "ahci" in the name that are installed:

root <at> MBa6x:/ find . -name "*ahci*" -print
./sys/bus/pci/drivers/ahci

./sys/module/ahci/drivers/pci:ahci
./sys/module/ahci_imx
./sys/module/libahci
./sys/module/libahci/parameters/ahci_em_messages 

This is in contrast to what I see when I install the image I built with BSP version 0101. Here is its output:

--------------------- Previous BSP (0101) Version --------------------------
"uname -a" reports:

Need fstrim program installed

Hello:

I have built the TQ board support package TQMa6x-BSP-REV.0104 using:

   --- ptxdist-2013.12.0
   --- OSELAS.Toolchain-2013.12.2

And "uname" now reports:

Linux MBa6x 3.16.0-rc5-20140718 #2 SMP Tue Sep 9 11:56:23 MDT 2014 armv7l GNU/Linux

I need the program "fstrim" for use with solid state drives. Please forgive me if I am posting to the wrong list, but I am unsure about where the trouble lies.

After building, I see these files on my host system under the directory TQMa6x-BSP-REV.0104:

 ./platform-MBa6x/packages/util-linux-2.23.1/sbin/fstrim
./platform-MBa6x/packages/util-linux-2.23.1/usr/share/man/man8/fstrim.8
./platform-MBa6x/build-target/util-linux-2.23.1/bash-completion/fstrim
./platform-MBa6x/build-target/util-linux-2.23.1/fstrim
./platform-MBa6x/build-target/util-linux-2.23.1/sys-utils/.deps/fstrim.Po
./platform-MBa6x/build-target/util-linux-2.23.1/sys-utils/fstrim.c

./platform-MBa6x/sysroot-target/sbin/fstrim
./platform-MBa6x/sysroot-target/usr/share/man/man8/fstrim.8

After I burn the image (uboot_tqma6s_hd.img) and install it on my TQ system, the fstrim command is apparently not installed. Can you tell me why it is not getting installed on the target TQ system and how I get it installed?

Thank you!

Has anyone ever installed PTXDist on Zynq7020

Going to build ptxdist for a zynq7020 dev kit.

Before I attempt this, I am curious if anyone has ever installed PTXDist on the Zynq7020? Xilinx has their own xilinx-gnu toolchain. I'm going to try the Xilinx toolchain first, but if it doesn't work I will try the arm-softfloat-linux-gnu- one. 

Most importantly: is there any possibility that I will break my silicon doing this? Did someone try it and blow up a Zynq or find something else bad that makes this a waste of time?
