The GW7902 is based on the i.MX 8M Mini / Nano SoC featuring: - LPDDR4 DRAM - eMMC FLASH - Gateworks System Controller - LTE CAT M1 modem - USB 2.0 HUB - M.2 Socket with USB2.0, PCIe, and dual-SIM - IMX8M FEC - PCIe based GbE - RS232/RS485/RS422 serial transceiver - GPS - CAN bus - WiFi / Bluetooth - MIPI header (DSI/CSI/GPIO/PWM/I2S) - PMIC To add support for the i.MX8M Nano GW7902: - Add imx8mn-venice dts/defconfig/include - Add imx8mn-gw7902 dts - Add imx8mn-2gb lpddr4 dram configs - Add misc support for IMX8M Nano SoC - rename imx8mm-venice.c to venice.c as it is no longer imx8mm specific - update README with differences for IMX8MN vs IMX8MM Signed-off-by: Tim Harvey <tharvey@gateworks.com> Reviewed-by: Fabio Estevam <festevam@gmail.com> |

U-Boot for the Gateworks i.MX8M Mini Venice Development Kit boards Quick Start =========== - Build the ARM Trusted firmware binary - Get ddr firmware - Build U-Boot - Flash to eMMC - Boot Get and Build the ARM Trusted firmware ====================================== $ git clone https://source.codeaurora.org/external/imx/imx-atf $ git checkout imx_5.4.47_2.2.0 $ make PLAT=imx8mm CROSS_COMPILE=aarch64-linux-gnu- bl31 $ cp build/imx8mm/release/bl31.bin . Get the DDR Firmware ==================== $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin $ chmod +x firmware-imx-8.9.bin $ ./firmware-imx-8.9.bin $ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin . Build U-Boot ============ $ make imx8mm_venice_defconfig $ make CROSS_COMPILE=aarch64-linux-gnu- Update eMMC =========== => tftpboot $loadaddr flash.bin => setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200 => mmc dev 2 && mmc write $loadaddr 0x42 $blkcnt # for IMX8MM => mmc dev 2 && mmc write $loadaddr 0x40 $blkcnt # for IMX8MN
