Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.8 release

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

Linux 6.6 LTS release – Highlights, Arm, RISC-V and MIPS architectures

Linux 6.6 release

The Linux 6.6 release has just been announced by Linus Torvalds on the Linux Kernel Mailing List (LKML): So this last week has been pretty calm, and I have absolutely no excuses to delay the v6.6 release any more, so here it is. There’s a random smattering of fixes all over, and apart from some bigger fixes to the r8152 driver, it’s all fairly small. Below is the shortlog for last week for anybody who really wants to get a flavor of the details. It’s short enough to scroll through. This obviously means that the merge window for 6.7 opens tomorrow, and I appreciate how many early pull requests I have lined up, with 40+ ready to go. That will make it a bit easier for me to deal with it, since I’ll be on the road for the first week of the merge window. Linus About two months ago, […]

Ultra-compact 45x43mm CPU module features TI Sitara AM6231, AM6252, or AM6254 Arm SoC

Texas Instruments Sitara AM6254 development board

MYiR Tech has just announced the tiny, yet full-featured MYC-YM62X CPU module powered by Texas Instruments Sitara AM6231, AM6252, or AM6254 Cortex-A53/M4 processor for HMI and IoT applications as well as the corresponding MYD-YM62X development board used for evaluation. The new MYiR module joins other Texas Instruments AM62x system-on-modules such as Toradex Verdin AM62, Forlinx FET625x-C, Variscite VAR-SOM-AM62, and others, but at just 45x43mm, it is the smallest AM62x CPU module we’ve seen so far yet the company says it still provides access to all features from the processor thanks to its 222 castellated holes. MYC-YM62X CPU Module Specifications: SoC (one or the other) Texas Instruments AM6254 (AM6254ATCGGAALW) with quad-core Cortex-A53 @ 1.4GHz, Cortex-M4F real-time core @ 400MHz, 3D GPU, 2x PRU-SS running up to 333MHz Texas Instruments AM6252 (AM6252ATCGGAALW) with dual-core Cortex-A53 @ 1.4GHz, Cortex-M4F real-time core @ 400MHz , no GPU, PRU-SS running up to 333MHz Texas Instruments […]

Linux 6.4 release – Main changes, Arm, RISC-V and MIPS architectures

Linux 6.4 release

Linux 6.4 has just been released by Linus Torvalds on the Linux Kernel Mailing List (LKML): Hmm. Final week of 6.4 is done, and we’ve mainly got some netfilter fixes, some mm reverts, and a few tracing updates. There’s random small changes elsewhere: the usual architecture noise, a number of selftest updates, some filesystem fixes (btrfs, ksmb), etc. Most of the stuff in my mailbox the last week has been about upcoming things for 6.5, and I already have 15 pull requests pending. I appreciate all you proactive people. But that’s for tomorrow. Today we’re all busy build-testing the newest kernel release, and checking that it’s all good. Right? Released around two months ago, Linux 6.3 brought us AMD’s “automatic IBRS” Spectre defense mechanism, additional progress on the Rust front with User-mode Linux support (on x86-64 systems only), the NFS filesystem (both the client and server sides) gained support for […]

Snagboot is an open-source cross-vendor recovery tool for embedded targets

snagboot

Bootlin has just released the Snagboot open-source recovery tool for embedded platforms designed to work with multiple vendors, and currently STMicro STM32MP1, Microchip SAMA5, NXP i.MX6/7/8, Texas Instruments AM335x and AM62x, and Allwinner “sunxi” processors are supported. Silicon vendors usually provide firmware flashing tools, some closed-source binaries, that only work with their hardware. So if you work on STM32MP1 you’d use STM32CubeProgrammer, while SAM-BA is the tool for Microchip processors, NXP i.MX SoC relies on UUU, and if you’ve ever worked on Allwinner processors you’re probably family with sunxi-fel. Bootlin aims to replace all those with the Snagboot recovery tool. The Python tool is comprised of two parts: snagrecover using vendor-specific ROM code mechanisms to initialize external RAM and run the bootloader (typically U-Boot) without modifying any non-volatile memories. snagflash communicates with the bootloader over USB to flash system images to non-volatile memories, using either DFU, USB Mass Storage, or […]

iW-RainboW-G55M is an OSM-LF compliant module based on TI AM62A Cortex-A53 processor

TI AM62Ax OSM Module

iWave Systems iW-RainboW-G55M is an OSM Size L compliant system-on-module based on Texas Instruments AM62A single to quad-core Cortex-A53 processor with up to 8GB RAM, 128GB eMMC flash, and a wireless module with WiFi 6, Bluetooth 5.2, and 802.15.4 radios. The iW-RainboW-G55M can leverage the vision processing and deep learning accelerator and the Arm Cortex-R5F real-time cores for control and device management found in the AM62A processor, as well as its display and camera interfaces, peripheral and networking options, to develop products for “man-machine applications at the edge”. iW-RainboW-G55M SoM specifications: SoC – Texas Instruments AM62A SoC (AM62A3, AM62A3-Q1, AM62A7, or AM62A7-Q1) Application processor – Up to four Arm Cortex- A53 cores @ 1.4GHz Real-time cores 1x Cortex-R5F @ 800MHz (MPU Channel with FFI) 1x Cortex-R5F @ 800MHz to support Device Management C7xV-256 Deep Learning Accelerator up to 2 TOPS System Memory – 2GB (default) to 8GB LPDDR4 RAM Storage […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.3 release

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 […]
