mt7621_rfb/mt7621_nand_rfb¶
U-Boot for the MediaTek MT7621 boards
Quick Start¶
Get the DDR initialization binary blob
Configure CPU and DDR parameters
Build U-Boot
Get the DDR initialization binary blob¶
- Download one from:
mt7621_stage_sram_noprint.bin has removed all output logs. To use this one, download and rename it to mt7621_stage_sram.bin
Put the binary blob to the u-boot build directory.
Configure CPU and DDR parameters¶
menuconfig > MIPS architecture > MediaTek MIPS platforms > CPU & DDR configuration
Select the correct DDR timing parameters for your board. The size shown here must match the DDR size of you board.
The frequency of CPU and DDR can also be adjusted.
Build U-Boot¶
$ export CROSS_COMPILE=mipsel-linux-
$ make O=build mt7621_rfb_defconfig # or mt7621_nand_rfb_defconfig
$ cp mt7621_stage_sram.bin ./build/mt7621_stage_sram.bin
$ # or cp mt7621_stage_sram_noprint.bin ./build/mt7621_stage_sram.bin
$ make O=build
Burn the u-boot-mt7621.bin to the SPI-NOR or NAND flash.
