Introduction

This BSP provides a basis for development, deployment and execution of Linux based applications on the phyCORE-Vybrid System on Module (SOM). For detailed information on the various software components included in the release and how to use them, please refer to the Quickstart.

Quickstart

Release PD13.1.0 should be used in conjunction with Quickstart version QS1.0:

What’s Supported

This BSP Release supports the following components:

  • Linux Kernel: 3.0
  • NAND Flash: U-Boot, Linux kernel [1]
  • QSPI NOR Flash
  • UART: RS-232 via SCI_1
  • USB: USB_0 in Host Mode; USB_1 in Host Mode
  • SD/MMC: MMC via MCU_PTA24-29 signals
  • Ethernet: 10/100 Mbit/s - ETH1 on RMII0; ETH1 on RMII1
Note:
The Ethernet PHY supported on this BSP is KSZ8051RNLI. Due to EOL this part has been replaced with KSZ8081RNBIA. SOMs with part number PCM-052-1210321CI.A3 will be populated with KSZ8081RNBIA. Ethernet functionality is the same for SOMs populated with the KSZ8051RNLI or KSZ8081RNBIA. The KSZ8081RNBIA PHY has a different model number that will be added to the software in the next BSP release.
  • RTC: Internal RTC
  • SPI: QSPI_A; QSPI_B
  • I2C driver: I2C_2 enabled
    • EEPROM: at24 on I2C_2
    • TSC: STMPE811 on I2C_2
  • PMIC
  • Audio: Freescale Codec SGTL5000 connected to I2S (I2C_2)
  • Display: Prime View PM070WL4 LVDS (LCD-017-070W)
  • LCD Backlight: PWM
  • Watchdog
  • MCC: Cortex-A5 (Linux) and Cortex-M4 (MQX)

What’s Not Supported

This BSP Release does not support the following components:

  • CAN: CAN_0; CAN_1
  • RTC: RV-4162-C7 on I2C_2
  • Light Sensor
  • High Speed Timer
  • Power Management: Suspend to RAM

Fixed in this Release

  • Cold boot system hang after DDR initialization in U-Boot

New in this Release

  • NAND boot [1]
  • QSPI NOR Flash
  • ETH1 on RMII1
  • SPI: QSPI_A; QSPI_B
  • LCD Backlight PWM
  • Watchdog

Known Issues

  • NAND Boot: Requires additional hardware setup. This will be fixed in the next hardware revision.Workaround: A hardware pull-up must be added to the NFC_R/B signal, we recommend a 4.7kΩ resistor but any value will work.
  • First boot requires display connection (Theatre Images):
    • Due to ts_calibrate being part of the initial board startup, the LCD-017-070 display must be connected to the Carrier Board during the first boot.
    • Workaround (if there is no display available): Use the host machine to remove the following startup scripts from the filesystem:
      • /etc/init.d/S70-calibrate-touchscreen
      • /etc/init.d/S70-detect-mouse
      • /etc/init.d/S98-timesys-theatre
      • /etc/init.d/K02-timesys-theatre
      • /etc/init.d/K30-calibrate-touchscreen
      • /etc/init.d/K30-detect-mouse
  • Touch on the display may be unresponsive after closing the timesys-theatre-demo.
    • Workaround: Reboot the system.
  • Audio may fail to work correctly after closing an audio file while it is playing.
    • Workaround: Reboot the system.
  • SDHC speed class 10 SD cards fail to mount the root filesystem when booting Linux. Below is an example of the boot failure:
mmc0: Timeout waiting for hardware interrupt.
mmcblk0: error -110 sending stop command, original cmd response 0x900, card status 0x400900
mmcblk0: error -110 transferring data, sector 196610, nr 2, cmd response 0x900, card status 0x0

mmcblk0: error -84 transferring data, sector 196610, nr 2, cmd response 0x900, card status 0x0
end_request: I/O error, dev mmcblk0, sector 196610
mmcblk0: error -84 transferring data, sector 196611, nr 1, cmd response 0x900, card status 0x0
