From: David Lechner Date: Fri, 26 Feb 2016 06:46:07 +0000 (-0600) Subject: arm: Add support for LEGO MINDSTORMS EV3 X-Git-Tag: v2016.05-rc1~449 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=2ac07f75d1977008e829d00bcce16143e171765d;p=u-boot arm: Add support for LEGO MINDSTORMS EV3 This is based on the davinci da850evm. It can boot from either the on-board 16MB flash or from a microSD card. It also reads board information from an I2C EEPROM. The EV3 itself initally boots from write-protected EEPROM, so no u-boot SPL is needed.

It is based +on the davinci da850 evm. The EV3 has a 16MB spi flash and a SDHC microSD card +reader. + +Booting +======= + +The EV3 contains a bootloader in EEPROM that loads u-boot.bin from address 0x0 +of the spi flash memory. Using the default configuration, u-boot will check to +see if there is a boot.scr file on the first FAT partition of the mmc. If there +is, it will run the script and boot the kernel from the uImage file also in +the FAT partition. Otherwise, it will load a kernel and rootfs from the flash. +The kernel must be stored at address 0x50000 on the flash and have a maximum +size of 3MiB. The rootfs must be a squasfs image and stored at 0x350000 in the +flash and have a maximum size of 9.3MiB. The flash starting at 0xCB0000 is +reserved for user data. + +Writing image to flash +====================== + +The EEPROM contains a program for uploading an image file to the flash memory. +The program is started by holding down the right button on the EV3 when powering +it on. You can also `run fwupdateboot` in the u-boot shell to reboot into this +mode. The image can then be uploaded using the official LEGO MINDSTORMS EV3 +software or a 3rd party program capable of uploading a firmware file. + +If you are booting from the microSD card, it is enough to just write uboot.bin +to the flash. If you are not using a microSD card, you will need to create an +image file using the layout described above. diff --git a/board/lego/ev3/legoev3.c b/board/lego/ev3/legoev3.c new file mode 100644 index 0000000000..a791b97f8f --- /dev/null +++ b/board/lego/ev3/legoev3.c @@ -0,0 +1,176 @@ +/* + * Copyright (C) 2016 David Lechner + * + * Based on da850evm.c + * + * Copyright (C) 2010 Texas Instruments Incorporated - http://www.ti.com/ + * + * Based on da830evm.c.
