Add defconfig for imxrt1050-evk is a development board from NXP. The i.MXRTxxxx family spreads from i.MXRT1020 to i.MXRT1170 with the first one supporting 1 USB OTG & 100M ethernet with a cortex-M7@500Mhz up to the latter with i.MXRT1170 with cortex-M7@1Ghz and cortex-M4@400Mhz, 2MB of internal SRAM, 2D GPU, 2x 1Gb and 1x 100Mb ENET. The i.MXRT family is NXP's answer to STM32F7xx, as it uses only simple SDRAM, it gives the chance of a 4 or less layer PCBs. Seeing that these chips are comparable to the STM32F7xxs which have Buildroot ported to them it seems reasonable to add support for them. https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/i-mx-rt1050-evaluation-kit:MIMXRT1050-EVK Signed-off-by: Jesse Taube <Mr.Bossman075@gmail.com> Cc: Giulio Benetti <giulio.benetti@benettiengineering.com> Reviewed-by: Giulio Benetti <giulio.benetti@benettiengineering.com> Tested-by: Giulio Benetti <giulio.benetti@benettiengineering.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> |

NXP i.MXRT1050 EVK board ------------------------ i.MX RT1050 are NXP's crossover MCUs. They combine the high performance and high level of integration of an applications processors with the ease-of-use and real-time functionality of a microcontroller. The i.MX RT1050 MCU runs on the Arm Cortex-M7 core at 600 MHz. https://www.nxp.com/design/development-boards/i-mx-evaluation-and-development-boards/i-mx-rt1050-evaluation-kit:MIMXRT1050-EVK To build a minimal support for this board: $ make imxrt1050-evk_defconfig $ make Buildroot prepares a bootable "sdcard.img" image in the output/images/ directory, ready to be flashed into the SD card: $ dd if=output/images/sdcard.img of=/dev/sdX Where 'sdX' is the device node of the uSD. Jumper settings: SW7: 1 0 1 0 Where 0 means bottom position and 1 means top position (from the switch label numbers reference). Connect the USB cable between the EVK and the PC for the console. Insert the micro SD card in the board, power it up and U-Boot messages should come up.
