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

Thanks,

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:

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/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?

[mini2440] Replacing udev with mdev

Hello all,

I am playing around to see if I can replace udev with mdev for the mini2440.

Most of it is working but as soon as I remove udev, I also lose the
/dev/fd, /dev/stdin, /dev/stdout, /dev/stderr entries

I have looked through the udev rules (default and mini2440 specific)
and also through the init scripts, and I don't see where these are
defined. There is one place at the /etc/init.d/udev script where these
links are created manually, but this code is not run if devtmpfs is
mounted (which is the case here)

Can anyone help?

Thank you,

Re: Could you assist pleas - one wire ts

Hi MC,

please let us continue our discussion at our public mailing list.

After changing one package (e.g. replacing the rule file coming with PTXdist by 
your own BSP-local one) it needs to re-create the whole rootfs (simple way) or 
to re-build all enabled packages which depends on the (replaced) tslib.

> For experimental purposes, how do I remove a package once I've added it?

Just disable it in the menu, run a "ptxdist clean root; ptxdist go" (note 
the 'clean root', not(!) only 'clean'). This will re-assemble the rootfs from 
the already built packages but will omit the now disabled package.

Or if you want to revert the replacement of a package, just remove the 
BSP-local rule file.

If you do your development via NFS root, handling a workflow like this is very 
easy.

Regards,
Juergen

PTXDist Application Note Kernel Driver Development out of date?

Hello,

I would like to experiment with building an "out-of-tree" driver and have browsed the PTXDist Application Note "Kernel Driver Development". My version of the board support package (TQMa6x-BSP-REV.0101) doesn't seem to have any of the .../rules/templates files that are mentioned in the document.

So, is the Application Note out of date or is the Application Note not applicable to the TQMa6x?

Any help would be appreciated!

Thank you!
