Tested some of the kernel versions possible (or not..) for the Next CHIP ARMv7, with mixed results.. I added an Ethernet/USB device (ax88179-based) on the USB hub, and the network connection works fine.. Linux-Next does not yet have the drivers for the Hynix NAND in the CHIP, although – with the rootfs separate on a USB stick … Continue reading →
After pre-ordering one many months ago, I finally got my Next CHIP ARMv7 system in the post.. It certainly is fairly small, but seems well-constructed.. Details are at http://docs.getchip.com/chip.html#chip-hardware After connecting the UART/USB cable, as normal, the system booted into a cut-down version of Debian.. There is no hdmi, or sdcard connector, or Ethernet, but the wi-fi … Continue reading →
I have tried the latest 4.7-next patched kernel, from https://github.com/anholt/linux/tree/bcm2837-64-next After some trials, I did manage to – just – get it to boot – after falling to an ’emergency console’, but the system is very unstable, with multiple recurring MMC errors.. ….. Give root password for maintenance (or press Control-D to continue): Error getting authority: Error … Continue reading →
Just tested the latest NVIDIA driver – 367.27 – and it fails to compile with Kernel 4.7-rc3. To fix this, the patch for 367.18 still works ( details at http://rglinuxtech.com/?p=1750 ). ………………..

I recently obtained one of the newly-released (- to the ‘public’..) Pine64 ARM64 systems… My first reaction, was that it is a bit on the large side.. The board is over twice the size of the Odroid C2.. As usual, the ‘standard’ U-Boot was a heavily-customised old version, that only mounted Android-format Kernel ‘blob’s, but a hacked … Continue reading →
Kernel 4.7-rc2 is out and brief details of changes from -rc1 are here: http://lkml.iu.edu/hypermail/linux/kernel/1606.0/03592.html After all the later-rc breakage with 4.6, I tested the latest patched NVIDIA drivers, and VMware, with this version, and all the previous 4.6/4.7 patches for VMware 12.1.1, and the 4.7 patches for NVIDIA 367.18 and 361.45.11 still work. See http://rglinuxtech.com/?p=1748 and http://rglinuxtech.com/?p=1750 … Continue reading →
My ‘system disk’ (/dev/sda) started to show bad sectors, recently, and so I decided to replace it. The disk was around 8 years old, and had been in almost-continuous use.. I have not had to do this for some considerable time, and I think the last time was in the late-90s, and using LILO! (No convoluted grub2 … Continue reading →
Thanks to juston_li on the NVIDIA Devtalk forum, there is specific detail of the changes needed for Kernel 4.7 compatibility.. Details are at https://devtalk.nvidia.com/default/topic/938665/linux/linux-4-7-rc1-367-18-build-errors/ The first issue is interesting, as it is due to a Kernel Dev. deciding to introduce a new variable – radix_tree_empty – in Kernel 4.7-rc1, that happens to have the same name as … Continue reading →
Thanks to g, from their comment on my previous article ( http://rglinuxtech.com/?p=1746 ), there may be a more correct vmnet fix than simply ‘commenting out the code’.. Replace dev->trans_start = jiffies with netif_trans_update(dev) in netif.c I have made this change, and VMware 12.1.1 is – so far – loading and running OK, as usual.. Robert Gadsdon.
