Scriptable boot sequences have already landed to an extent, but I have
a few changes landing soon (I hope) that will make them a bit more
reliable. It is all basically expect/send to some approximation. If
you can use that sort of logic Tyler and I both have experience with
it and can help (not sure about the rest of the LAVA team).
I currently use this to flash new images onto boards using uboot and
tftp in my home lab then hack around the fact that the image I just
flashed doesn't auto-login.
I hope to change how this works a bit soon so I can configuration
separate for boards, images and tests. Currently the extra config I
need for an image is either held in the board or test config. This
should allow for writing a test that references an image config file.
#include all over again :-)
The job looks like this at the moment:
{
"device_type": "some device",
"actions": [
{
"command": "deploy_linaro_kernel",
"parameters": {
"kernel": "file:///path/to/zImage",
"ramdisk": "file:///path/to/jffs2",
"dtb": "... used to crash without this, left it in, unused ..."
}
},
{
"command": "boot_linaro_image",
"parameters": {
"interactive_boot_cmds": true,
"options": [
"setenv ipaddr '192.168.1.50'",
"setenv serverip ${lava_server_ip}",
"setenv update_k1_lava 'tftp ${lava_kernel} && sha1sum
$loadaddr $filesize; nand erase k1; nand write k1 $filesize; set
loadaddr 0x08000000; tftp ${lava_ramdisk} && sha1sum $loadaddr
$filesize; nand erase r1; nand write r1 $filesize; set loadaddr
0x8000'",
"run update_k1_lava",
"sendline boot",
"expect Machine: Entropic STB Krome platform",
"expect login:",
"sendline root"
]
}
},
{
"command": "lava_test_shell",
"parameters": {
"testdef_urls": [
"http://192.168.1.11/tests/ls.yaml";
],
"timeout": 1800
}
},
{
"command": "submit_results",
"parameters": {
"stream": "/anonymous/dooferlad/",
"server": "http://192.168.1.10/RPC2/";
}
}
],
"timeout": 18000,
"job_name": "Run ls for ultimate testing!"
}
Note the interactive_boot_cmds has some "sendline <string>" lines and
some "<string>" lines. The difference is that sendline doesn't wait
for the bootloader prompt. Most of the time you don't need to do
sendline/expect, but if you want to do something a bit unusual, such
as wait for a login prompt and type root (as above), they come in
useful.
