The ISC DHCP server (dhcpd) was traditionally used to set up a DHCP server in Linux, but the software is reaching end-of-life, and the Internet Systems Consortium is now recommending their own Kea DHCP server or alternatives such as Dnsmasq or udhcpd (as found in Busybox) as a replacement. I was unaware of this having just used the isc-dhcp-server package to set up a DHCP server in NanoPi R6C router/mini PC earlier this month. But a blog post on Ubuntu informed us dhcpd was going away, and Canonical plans to switch over the Kea DHCP server instead. The main difference from the user perspective is that Kea relies on JSON configuration files so all your dhcpd files will have to be rewritten. Other highlights for the Kea DHCP server include: Modular component design, extensible with hooks modules. Kea includes daemons for a DHCPv4 server, a DHCPv6 server, and a dynamic [...] The post Use Kea DHCP server as ISC DHCP server (dhcpd) is being phased out appeared first on CNX Software - Embedded Systems News.

A few years ago I reviewed the ICE Tower CPU cooling fan for Raspberry Pi 4 which is an oversized heatsink with a cooling fan and some RGB LEDs that obviously does its job at cooling the board, but the main benefit is really its aesthetics. 52Pi has now designed another ICE Tower cooling fan for the Orange Pi 5 SBC, and the new Orange Pi 5B, with the same concept except for its low-profile design. It’s probably not needed for the Orange Pi 5 which should do fine with a heatsink, but it may help for the Orange Pi 5B due to the extra heat from the WiFi 6 module. A company representative for 52Pi told us that: I have seen this Orange Pi 5B motherboard posted on your site, there are quite a lot of reviews and discussions, so far after our engineer’s test, this motherboard has quite [...] The post Orange Pi 5 SBC gets its own $20 low-profile ICE Tower cooling fan appeared first on CNX Software - Embedded Systems News.

As I checked out Linux 6.3 changelog earlier this morning, I noticed the EmbedFire LubanCat 2 SBC in the Rockchip section, and having never heard of the EmbedFire company or LubanCat single board computers, I decided to have a closer look. EmbedFire is a company based in China, more exactly in DongGuan, that makes a range of LubanCat single board computers based on Rockchip RK3566 or RK3568 processors, some of which partially follow Raspberry Pi Zero or Raspberry Pi 3/4 Model B form factors, while others come with custom designs.

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog [...] The post Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures appeared first on CNX Software - Embedded Systems News. View the full article

Description RK3328 devices often have I2S1 bus available on expansion pins. This PR introduces an overlay to enable the I2S1 bus for Rock Pi E to enable external PCM5102 DAC; I2S1 is shared for internal audio codec and external GPIO pins, so the overlay also disables the internal audio codec. This has been tested and proved to work on Rock Pi E, should work on other boards with similar board wiring setup, but can be also used as a base for other board/DAC combos in the future.
