piCore 15.0 Release

[Juanito]

xorg-server and Xorg-3d updated on piCore64-15.x

Xorg and Xorg-3d tested on an RPi4 running piCore64, @Synerworks maybe you could test on an RPi3

[Synerworks]

All good now with Xorg and Xorg-3d on piCore64-15.x, verified on PI02-5s!

[Synerworks]

While testing on PI0-1s, found that extensions containing the 'vcgencmd' tools are both located in 'rpi-vc.tcz' and 'raspi-utils.tcz', with some that overlap each other. However, for piCore 14.x and 15.x, the command generates an 'Illegal instruction' with this command from the 'rpi-tc.tcz' extension, but works from the 'raspi-utils.tcz' extension. The 'vcgencmd' from 'rpi-vc.tcz' repo on piCore 13.x does work as expected, even though they use the additional libraries. Inspecting the 'ldd' results for each of the 'vcgencmd's from each of the repos shows that they were generated against different libraries.

Code: [Select]

tc@box:~$ ldd `which vcgencmd`
libc.so.6 => /lib/libc.so.6 (0xb6d5b000)
/lib/ld-linux-armhf.so.3 (0xb6ee1000)
tc@box:~$ # From repo 'raspi-utils.tcz' for piCore 14.x, and 15.x

Code: [Select]

tc@box:~$ ldd `which vcgencmd`
libvchiq_arm.so => /usr/local/lib/libvchiq_arm.so (0xb6f30000)
libvcos.so => /usr/local/lib/libvcos.so (0xb6f00000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb6f83000)
libdl.so.2 => /lib/libdl.so.2 (0xb6f5d000)
librt.so.1 => /lib/librt.so.1 (0xb6f5a000)
libc.so.6 => /lib/libc.so.6 (0xb6dab000)
/lib/ld-linux-armhf.so.3 (0xb6f8e000)
tc@box:~$ # From repo 'rpi-vc.tcz' from piCore 13.x, 14.x, and 15.x
The 'temp.tcz' repo depends on the 'rpi-vc.tcz' extension, even though it could use the 'raspi-utils.tcz' extension instead, so the application fails due to this exception. As an interim correction, loading the 'raspi-utils.tcz' extension in the 'onboot.lst' enables the 'temp' command to function when the 'rpi-vc.tcz' repo is renamed/removed from the 'optional' folder after installation when using the 'tce-load -wi temp' command. However, this approach would not facilitate those that depend on the additional commands from the 'rpi-vc.tcz' extension that are not in the 'rasp-utils.tcz' repo though.

rpi-vc is mostly obsolete, raspi is no longer maintaining any tools in that extension.    raspi-utils is the current maintained extension.

You do not even need temp.tcz or raspi-utils to get temperatures.

Code: [Select]

cat /sys/devices/virtual/thermal/thermal_zone0/temp

or printed nicer

Code: [Select]

cat /sys/devices/virtual/thermal/thermal_zone0/temp | awk '{ printf "%2.1fC\n", $1/1000 }'

Will do. I only used the 'temp.tcz' dependency to illustrate a use case, so if the 'rpi-vc.tcz' extension is obsoleted, the repo dependency should switch over to 'raspi-utils.tcz' instead. Nonetheless, the issue manifests itself when attempting to use the VC tools and the incorrect repo is loaded or both and then throws the exception. Also, the superseded objects could be copied from the working 'raspi-utils.tcz' repo into the obsoleted extension to avoid this inconsistency when using the required component but picking the wrong 'provides.sh' result. Just attempting to avoid caveats as they come up.

Are there any plans for updating node.tcz in the future? By now I really have to jump through hoops to get JS and TS applications to work.

[Juanito]

In armhf or aarch64?

The node.js extensions (as opposed to the node extensions) seem quite recent?

Known Issues:
 - Internal Wifi on some Raspi chipsets, there is a driver problem with wpa_supplicant 2.11 (Add brcmfmac.feature_disable=0x82000 to cmdline.txt on the boot drive)

Which Raspi chipsets please?  Or better still, which Pi models?  By trial and error it seems to include the Pi Zero?

[Paul_123]

I don’t have every combination to test.  It may just be the zero based product.   They all use the same driver.  Just different firmware.
