The following is a reference of commands etc. that we use to test our hardware with U-Boot/uClinux (Blackfin Core Modules and development boards).

Please note that not all listed tests are available for all Core Modules. Refer to the [[Blackfin uClinux support matrix|support matrix]] for more information.

== U-Boot ==

=== Load U-Boot via serial ===
* Set boot mode to UART boot
bfin-uclinux-ldr -l blackfin/blt-scripts.git/images/cm-bf527/u-boot-UARTBOOT.ldr /dev/ttyUSB0 && kermit ~/stuff/kermit0USB

=== Flash U-Boot and uClinux ===
* U-Boot prompt:
setenv ipaddr 192.168.1.2
setenv serverip 192.168.1.1
CM-BF537E, CM-BF537U, TCM-BF537 only:
setenv ubootfile u-boot.bin
All:

=== USB test ===
U-Boot supports mass storage devices.
*Connect USB mass storage device to mini-USB-plug, formatted with 1 partition (EXT2), uImage on it
*Reset board
*Start USB
usb start
usb storage
*List files
ext2ls usb 0:1
*Load uImage
ext2load usb 0:1 0x1000000 uImage
*Boot Linux
bootm
Linux boots, hence uImage was read correctly.
