Session Option is invalid when using reset/flash command

[windowsair]

It looks like session option is invalid when using reset/flash command:

pyocd reset -Ocmsis_dap.prefer_v1=1

When using these command, session seems not create, and fallback to use default option, that is cmsis.prefer_v1=False .

If we use the list command, the session option behaves correctly:

pyocd list  -Ocmsis_dap.prefer_v1=1
