Release 1.12.2 of Linux Cortex-M
Release 1.12.2 of Linux Cortex-M is now available. Here is what’s new:
- uClinux BSP for the Emcraft Kinetis K70/K61 SOM Starter Kit:
- Support to Linux low-power mode on Kinetis (suspend-to-RAM);
- Starting Release 1.12.2, the kit will use Rev 2A of the TWR-K70-SOM-BSB baseboard.
- Linux BSP for the Emcraft Vybrid VF6 SOM Starter Kit:
- Support for NAND Flash, in addition to the already supported QSPI Flash;
- Optimized Linux boot time and performance from NAND Flash;
- Ability to load and run MQX on the Cortex-M4 processor core from U-Boot, facilitating early start of real-time code;
- Ability to display static "splash image" (.bmp logo file) on a connected LCD from U-Boot very early in boot process;
- Various enhancements and defect fixes.
Here is the list of enhancements and defect-fixes in Release 1.12.2:
- Allow debugging of multi-threaded applications on Cortex-M (ID: RT 77243);
- Support suspend-to-RAM in Kinetis Linux (ID: RT 79435);
- Develop TWR-K70-SOM-BSB Rev 2A (ID: RT 87225);
- Optimize NAND to DDR copy time in U-boot for VF6 SOM (ID: RT 88666);
- Provide ability to load MQX onto Cortex-M4 from U-Boot (ID: RT 89985);
- Linux VF6: copy-pasting arbitrary text to console causes kernel crash (ID: RT 91033);
- Resolve defect: Enabling GPIOLIB interrupts crashes the kernel if SD Card is enabled on Kinetis (ID: RT 91947);
- Migrate to the NAND Flash and run Cortex-A5 at 500 MHz (ID: RT 92729);
- Resolve defect: It is not possible to mount a JFFS2 file system on NAND Flash (ID: RT 96337);
- MAC address is not passed from U-Boot to Linux (ID: RT 93076);
- Resolve defect: U-boot hangs in an infinite loop on Vybrid PLL2/1 status check (ID: RT 93236);
- Port the U-boot splash image and the Linux framebuffer driver to LCD-ADDON (ID: RT 93274);
- Fix improper handling of bits in I2C Control and Status registers (ID: RT 93346);
- Add an ifnarch command to the initramfs spec syntax (ID: RT 93386);
- Optimize busybox build for Vybrid VF6 (ID: RT 93464);
- Linux Cortex-M:uclibc:Implement pthreads locking using ldrex/strex (ID: RT 93564);
- Add support for the Micrel KSZ8863 Ethernet PHY to U-Boot (ID: RT 94867);
- Develop an Apple MFi demo for the VF6 SOM (ID: RT 95248);
- Add ALSA libraries and utilities to Linux Cortex-M (ID: RT 95693);
- Disable EZPORT in U-Boot on Kinetis (ID: RT 95769);
- Resolve defect: It is not possible to mount a JFFS2 file system on NAND Flash (ID: RT 96337);
- Add i2ctools to Linux Cortex-M (ID: RT 96343);
- Develop an SOM-BSB-VF6-IOT-EXT board (ID: RT 96601);
- Develop Linux device driver for Kinetis on-chip RTC (ID: RT 97149);
- Make the Kinetis SD Card driver detect SD Card from first attempt (ID: RT 98225);
- Migrate to TWR-K70-SOM-BSB rev 2A in Kinetis SOM Starter Kit (ID: RT 98612).
