Create a bootable SD card
The most common boot sources supported on the STKP2020 (Rev. ≥ 0106 required) are:
- NOR-Flash (local bus) ← default
- SD card (eSDHC interface)
In order to boot (i.e. load a bootloader) from SD card, the RCW has to be modified accordingly (see above).
- Prerequisites
- Download the current U-Boot for TQMP2020.
- Either use the prebuilt U-Boot binary from the downloaded ZIP archive (BIN\u-boot_tqmp2020_sdcard_2012-09-25_mkr.bin) or build your own by executing
./MAKEALL tqmp2020_sdcard
- Get and build (cf. README) the boot-format utility avalailable at http://git.freescale.com/git/cgit.cgi/ppc/sdk/boot-format.git/.
- Prepare the SD card
The SD card has to be partitioned as follows (assuming the SD card is /dev/sdc):
tq@ubuntu:~/boot-format$ sudo fdisk /dev/sdc
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

- Create the bootable SD card
The boot-format utility requires the file SRC\config_sram_tqmp2020.dat (contained in U-Boot for TQMP2020) and the (pre-built) U-Boot binary to create a bootable SD card
tq@ubuntu:~/boot-format$ sudo ./boot_format config_sram_tqmp2020.dat u-boot_tqmp2020_sdcard_2012-09-25_mkr.bin -sd /dev/sdc It is a little endian machine.
