T1024RDB board Overview
on T1024RDB:
set SW1[1:8] = '00010011', SW2[1] = '1', SW3[4] = '0' for NOR boot
on T1023RDB:
- set SW1[1:8] = '00010110', SW2[1] = '0', SW3[4] = '0' for NOR boot
+ set SW1[1:8] = '00010111', SW2[1] = '1', SW3[4] = '0' for NOR boot
Switching between default bank0 and alternate bank4 on NOR flash
To change boot source to vbank4:
via software: run command 'cpld reset altbank' in u-boot.
via DIP-switch: set SW3[5:7] = '100'
on T1023RDB:
- via software: run command 'gpio vbank4' in u-boot.
+ via software: run command 'switch bank4' in u-boot.
via DIP-switch: set SW3[5:7] = '100'
To change boot source to vbank0:
via software: run command 'cpld reset' in u-boot.
via DIP-Switch: set SW3[5:7] = '000'
on T1023RDB:
- via software: run command 'gpio vbank0' in u-boot.
+ via software: run command 'switch bank0' in u-boot.
via DIP-switch: set SW3[5:7] = '000'
2. NAND Boot:
=> tftp 1000000 u-boot-with-spl-pbl.bin
=> nand erase 0 $filesize
=> nand write 1000000 0 $filesize
- set SW1[1:8] = '10001000', SW2[1] = '1', SW3[4] = '1' for NAND boot
+ set SW1[1:8] = '10000010', SW2[1] = '1', SW3[4] = '1' for NAND boot
3. SPI Boot:
a. build PBL image for SPI boot
$ make
b. program u-boot-with-spl-pbl.bin to SD/MMC card
=> tftp 1000000 u-boot-with-spl-pbl.bin
- => mmc write 1000000 8 0x800
+ => mmc write 1000000 8 0x7f0
=> tftp 1000000 fsl_fman_ucode_t1024_xx.bin
=> mmc write 1000000 0x820 80
set SW1[1:8] = '00100000', SW2[1] = '0' for SD boot
+ SW3[3] = '1' for SD card(or 'switch sd' by software)
+ SW3[3] = '0' for eMMC (or 'switch emmc' by software)
