Screen Support for NXP and Toradex i.MX8MP: Release Notes

This document lists the details, updates, and issues associated with this screen board support release.


Date of this edition: March 21, 2024

A screen support package contains the display and GPU libraries and drivers needed to extend the general base screen package for a particular board support package (BSP). For compatibility, all three support packages: board, base screen, and extended screen support, should be based on the QNX Software Development Platform 8.0 (SDP 8.0).

QNX SDP is a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for ARM v8 and x86_64 targets running the QNX OS 8.0.

Throughout this document, you may see reference numbers associated with particular issues or changes. When corresponding with our Technical Support staff about an issue, use the relevant reference number. You might also find the reference numbers useful for tracking issues as they become fixed.

  • Switch the WFD port1 and port2, to disabled: 
    #Setting for WFD port 1 (LCDIF1/MIPI0)
                    wfd-port-lcdif1-mipi = disabled
                    #Setting for WFD port 2 (LCDIF2/LVDS0,LVDS1,DUAL)
                    wfd-port-lcdif2-lvds = disabled
  • Comment out or remove the begin display 1 and begin display 2 sections.
  • Comment out or remove the For display #1 and For display #2 sections.

Known issues

  • Verdin only - Screen crashes when attempting to use the HDMI port. (Ref. J2953676)

    Workaround: Perform the following changes in the BSP:

    • In the startup/boards/imx8mp/verdin/init_pads.c BSP file, add the following lines to the imx_init_display_pads() function: 
      /* Configure HDMI pins */
/* DDC_SCL */
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_MUX_CTL_PADx(IMX_IOMUXC_SW_MUX_CTL_PAD_HDMI_DDC_SCL), IMX_MUX_CTL_MUX_MODE_ALT0);
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_PAD_CTL_PADx(IMX_IOMUXC_SW_PAD_CTL_PAD_HDMI_DDC_SCL), IMX8MP_PAD_SETTINGS_I2C);
/* DDC_SDA */
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_MUX_CTL_PADx(IMX_IOMUXC_SW_MUX_CTL_PAD_HDMI_DDC_SDA), IMX_MUX_CTL_MUX_MODE_ALT0);
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_PAD_CTL_PADx(IMX_IOMUXC_SW_PAD_CTL_PAD_HDMI_DDC_SDA), IMX8MP_PAD_SETTINGS_I2C);
/* CEC */
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_MUX_CTL_PADx(IMX_IOMUXC_SW_MUX_CTL_PAD_HDMI_CEC), IMX_MUX_CTL_MUX_MODE_ALT0);
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_PAD_CTL_PADx(IMX_IOMUXC_SW_PAD_CTL_PAD_HDMI_CEC), IMX_PAD_CTL_SRE_FAST);
/* HPD */
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_MUX_CTL_PADx(IMX_IOMUXC_SW_MUX_CTL_PAD_HDMI_HPD), IMX_MUX_CTL_MUX_MODE_ALT0);
out32(IMX_IOMUXC_BASE + IMX_IOMUXC_SW_PAD_CTL_PADx(IMX_IOMUXC_SW_PAD_CTL_PAD_HDMI_HPD), IMX_PAD_CTL_SRE_FAST);
    • In the startup/boards/imx8mp/verdin/init_clock.c BSP file, add the following lines to the imx_init_dc_clock() function: 
      /* Enable power domain for HDMI */
{
/* Enable HDMIMIX power domain */
(void)imx_sec_firmware_psci(IMX_FSL_SIP_GPC, IMX_FSL_SIP_CONFIG_GPC_PM_DOMAIN, ATF_PU_HDMIMIX, 0x01, 0x00);
/* Enable HDMI_PHY power domain */
(void)imx_sec_firmware_psci(IMX_FSL_SIP_GPC, IMX_FSL_SIP_CONFIG_GPC_PM_DOMAIN, ATF_PU_HDMI_PHY, 0x01, 0x00);
}
