more of rpardini's dirty laundry, very late April/'23 Remove legacy branches after trying, and failing, to ressurect them rockchip: completely remove legacy branch; fixes #5118 there's absolutely no point in trying to keep this alive, current/edge are good enough, legacy's abandoned for years and broken jetson-nano legacy: give up on this legacy and remove it; fixes #5117 jetson-nano legacy: try, and fail, to fix this legacy; (does NOT) fixes #5117 jetson-nano legacy: kernel config: CONFIG_SECTION_MISMATCH_WARN_ONLY=y jetson-nano legacy: add -mno-outline-atomics to fix linking jetson-nano legacy: add xxd host-dependency jetson-nano legacy: downgrade a lot of gcc errors to allow this legacy to build Fix (sucessfully) broken stuff rtl8822bs: fix: remove binaries (firmware?) being added to kernel driver source and breaking patching; related to #5117 kernel-make: introduce KERNEL_EXTRA_CFLAGS; fill it to add to what's passed to KCFLAGS; related to #5117 macchiatobin-doubleshot: fix u-boot/atf build: export SCP_BL2 had been wrongly converted to declare -g SCP_BL2 when it is in fact required; fixes #5116 rk3399-4.4: remove mbox-confusing long explanation from ancient patch in ancient kernel; possibly fixes #5119 driver_uwe5622_allwinner: only apply "pre-6.1" park-link patch if kernel >= 5 (eg: not for rockchip64-legacy); possibly fixes #5120 rockchip64_common: add explicit make target u-boot.dtb before u-boot.itb in the target map for SPI; fixes #5114 when BOOT_SUPPORT_SPI=yes (and not using the rkspi_loader) it seems the makefile target u-boot.itb does not correctly depend on the u-boot.dtb target, and works "by accident" on multicore machines, which are faster and build it fast enough in parallel. this adds u-boot.dtb to the target map, so make's hand is forced to do the right thing. artifact-uboot: fix: include UBOOT_TARGET_MAP in variables hash of version kernel-debs: postinst/etc: fix: unify is_boot_dev_vfat() function; make work during image build too via env var determinining if /boot is vfat is more complex than it looks; use a common function to unify across all scripts during image build, the kernel install is always done with a non-fat, non-mounted /boot use a special variable passed through the env so unified function can know ahead of time introduce extra_apt_envs param to chroot_sdcard_apt_get(); array with extra environment vars if vfat /boot: linux-update-symlinks is not called (Debian would just choke on this) don't even try to symlink Armbian stuff, move instead more/better logging board-side (unfortunately mixed in all the set -x debugs) View the full article

Damien George has recently announced the release of MicroPython 1.20 with support for the Raspberry Pi Pico W board., a new lightweight package manager called mip, a smaller footprint thanks to the use of compressed type structs, and many other changes. mip package manager The new mip package manager uses a custom protocol optimized for embedded systems to query and install packages, and intends to replace upip for installing packages from micropython-lib or any URL. Mip can be run directly on a device, as long as it has network connectivity, or via mpremote from a host computer. Damien explains all pure-Python drivers have been moved from the micropython repository to the micropython-lib repository as part of the change in order to make it easier to install the packages needed for a given project. MicroPython is getting smaller The MicroPython binary size has been reduced by many kilobytes for all ports [...] The post MicroPython 1.20 released with Raspberry Pi Pico W support, mip package manager, smaller footprint appeared first on CNX Software - Embedded Systems News.

Corsair MP600 Mini is a high-performance M.2 2230 SSD based on the Phison E21T controller that delivers up to 4800MB/s sequential read and write performance and designed to be used in Valve’s Steam Deck, Microsoft’s Surface Pro 8 and 9, and other products that won’t take a M.2 2280 SSD. We are seeing more and more single board computers and other electronics products use M.2 sockets for storage, but the smaller boards won’t take the traditional M.2 2280 SSDs that usually deliver better performance than smaller M.2 2230/2242/2260 drives, and so performance may be impacted on this type of hardware. But the Corsair MP600 Mini changes that with high sequential and random read/write performance. Cordair MP600 Mini specifications: SSD Unformatted Capacity – 1TB NAND Technology – 3D TLC NAND Host interface – PCIe Gen 4.0 x4 Performance Max Sequential Read – Up to 4,800MB/s tested with CrystalDiskMark (CDM) Max Sequential [...] The post Corsair MP600 Mini M.2 2230 NVMe SSD delivers up to 4800 MB/s read/write performance appeared first on CNX Software - Embedded Systems News.

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.
