+Settings of DIP-switch +======================
- SW4[1:4]= 1111 and SW6[4]=0 for boot from 16bit NOR flash
- SW4[1:4]= 1000 and SW6[4]=1 for boot from 8bit NAND flash
- SW4[1:4]= 0110 and SW6[4]=0 for boot from SPI flash
+Note: 1 stands for 'on', 0 stands for 'off'
+Please refer to P1010-RDB User Guide for details.
Where might one find this user guide?
+Setting of hwconfig +=================== +If FlexCAN or TDM is needed, please set "fsl_p1010mux:tdm_can=can" or +"fsl_p1010mux:tdm_can=tdm" explicitly in u-booot prompt as below for example: +setenv hwconfig "fsl_p1010mux:tdm_can=tdm;usb1:dr_mode=host,phy_type=utmi" +By default, don't set fsl_p1010mux:tdm_can, in this case, spi chip selection +is set to spi-flash instead of to SLIC/TDM/DAC and tdm_can_sel is set to TDM +instead of to CAN/UART1.
+Build and burn u-boot to NOR flash +======================================= +1. Build u-boot.bin image
- export ARCH=powerpc
- export CROSS_COMPILE=/your_path/powerpc-linux-gnu-
- make P1010RDB_NOR
+2. Burn u-boot.bin into NOR flash
- => tftp $loadaddr $uboot
- => protect off eff80000 +$filesize
- => erase eff80000 +$filesize
- => cp.b $loadaddr eff80000 $filesize
+3. Check SW4[1:4]= 1111 and SW6[4]=0, then power on.
+Build and burn u-boot to NAND flash +======================================== +1. Build u-boot.bin image
- export ARCH=powerpc
- export CROSS_COMPILE=/your_path/powerpc-linux-gnu-
- make P1010RDB_NAND
+2. Burn u-boot-nand.bin into NAND flash
- => tftp $loadaddr $uboot-nand
- => nand erase 0 $filesize
- => nand write $loadaddr 0 $filesize
+3. Check SW4[1:4]= 1000 and SW6[4]=1, then power on.
+Build and burn u-boot to SPI flash +======================================= +1. Build u-boot-spi.bin image
- make P1010RDB_SPIFLASH_config; make
- Boot up kernel with rootfs.ext2.gz.uboot.p1010rdb
- Download u-boot.bin to linux and you can find some config files
- under /usr/share such as config_xx.dat. Do below command:
- boot_format config_ddr3_1gb_p1010rdb_800M.dat u-boot.bin -spi \
u-boot-spi.bin- to generate u-boot-spi.bin.
+2. Burn u-boot-spi.bin into SPI flash
- => tftp $loadaddr $uboot-spi
- => sf erase 0 100000
- => sf write $loadaddr 0 $filesize
+3. Check SW4[1:4]= 0110 and SW6[4]=0, then power on.
Also describe how do select boot mode via software rather than switches, and describe alternate NOR bank.
