Note: This test doesn't rely on boardenv_* configuration value but they can

change test behavior.

|

For example:
|
|
|
|
# Setup env__saveenv_test_skip to True if saveenv test is not possible or
|
|
# desired and should be skipped.
|
|
env__saveenv_test_skip = True
|
|
|
|
# Setup env__saveenv_test to set the bootmode if 'modeboot' u-boot environment
|
|
# variable is not set. Test will be skipped if bootmode is not set in both
|
|
# places i.e, boardenv and modeboot u-boot environment variable
|
|
env__saveenv_test = {
|
|
'bootmode': 'qspiboot',
|
|
}
|
|
|
|
# This test will be also skipped if the bootmode is detected to JTAG.
