New In This Release
- Yocto
- SDK: Ported to TI's Processor SDK v03.02.00.05
- Kernel
- Version: Migrated from Linux Kernel v4.4.12 to v4.4.32
- PCIe: x2 lane support
- Parallel Camera: Support added for VIN3 interface. Enabled and tested with VM-009-M12.
- QSPI
- Support added for QSPI1
- QSPI NOR (N25Q128A) using QSPI1_CS2 is tested and enabled (see 72908877)
- MCSPI: Support added for SPI1. Enabled and tested using X_SPI1_nCS0 on connector X28 (Expansion Connector).
- U-Boot
- SD Card
- U-Boot will always boot the kernel and rootfs from SD card, when present.
- The U-Boot environment is strictly stored on the SD card, and cannot be saved without an SD card present.
- SD Card
Fixed In This Release
- Kernel
- GPIO: GPIO mapping now appears in contiguous order according to register assignments (see output of command: "cat /sys/kernel/debug/gpio"). Previous ordering was: GPIO1,2,3,4,6,7,8,5.
- Power: VBUS_DET implementation prevents complete poweroff. USB2 uses the PMIC VBUS_DET circuit, and when VBUS is provided by the processor (USB2 in host mode), the USB2_VBUS signal connected to the PMIC generates a WAKE event. As a result, the PMIC powers the system back up as soon as the shutdown finishes.
Known Issues
- Yocto
- Package ccs6 fetch fails due to TI export approval requirement. Workaround is to download the package manually as noted in the BSP-Yocto-TISDK-AM57xx-PD17.1.0 Quickstart.
- Kernel
- Display: TI's Matrix-GUI demo only displays to either HDMI or LCD, not both. The workaround is to enable one or the other. LCD-018 is currently the default.
- QSPI: Possible read failures on flash devices with HOLD function (Erratum i916). A software workaround has been implemented to limit QSPI to DIO-SPI mode. The hardware workaround is to disable internal pull-ups and add 10k pull-ups on X_QSPI1_D2 & X_QSPI1_D3.
- For the software workaround, this commit also needs to be added to the source before building the .dtb. It is currently configured correctly when external pull-ups are installed.
