from autotest_lib.server.cros.faft.firmware_test import FirmwareTest
class firmware_FWtries(FirmwareTest):
Boot with firmware B until fwb_tries/fw_try_count counts down to
0. vboot1 only needs to set fwb_tries in order to boot into FWB,
but vboot2 needs to set two fields: fw_try_next and fw_try_count
in order to do so.
Setup Steps:
1. Make the device in normal/dev mode.
Test Steps:
2. Set # of tries to 2 (through try_fwb)
a. For vboot1:
set fwb_tries=2
[fwb_tries can be > 0 and <= 15. Value will be auto reset to 15 If
the value is < 0 or > 15
b. For vboot2:
set fw_try_next=B fw_try_count=2
3. Reboot 1
4. Reboot 2
5. Reboot 3
Verification Steps:
1. After reboot 1, fw_tries_checker checks that
mainfw_act = B
fwb_tries/fw_try_count = 1
2. After reboot 2, fw_tries_checker checks that
mainfw_act = B
fwb_tries/fw_try_count = 0
3. After reboot 3, fw_tries_checker
mainfw_act = A
fwb_tries/fw_try_count = 0
version = 1
