master branch currently broken with bitbang adapter?

[floe]

When I want to run current master branch with my nrf51 & BusPirate, I get the following error:

$ ruby -I. nrf51.rb name=buspirate:dev=/dev/ttyUSB0
/home/floe/src/programmer.git/adiv5-swd.rb:36:in `reset': undefined method `flush!' for #<BitbangSwd:0x000000023d2eb0> (NoMethodError)
    from /home/floe/src/programmer.git/adiv5-swd.rb:30:in `switch_to_swd'
    from /home/floe/src/programmer.git/adiv5-swd.rb:21:in `initialize'
    from /home/floe/src/programmer.git/backend-driver.rb:17:in `new'
    from /home/floe/src/programmer.git/backend-driver.rb:17:in `create'
    from /home/floe/src/programmer.git/backend-driver.rb:43:in `from_string_set'
    from /home/floe/src/programmer.git/backend-driver.rb:47:in `from_string'
    from nrf51.rb:170:in `<main>'

I can work around that by adding an empty flush! method in swd-bitbang.rb, but then I immediately run into the next error:

$ ruby -I. nrf51.rb name=buspirate:dev=/dev/ttyUSB0
nrf51.rb:8:in `detect': undefined method `IDR' for nil:NilClass (NoMethodError)
    from /home/floe/src/programmer.git/armv7.rb:22:in `initialize'
    from nrf51.rb:12:in `initialize'
    from nrf51.rb:171:in `new'
    from nrf51.rb:171:in `<main>'

And I'm not familiar enough with the code to tell why that happens... (even though it seems to be just like the solution in stm32.rb).

BTW, git bisect points to this commit as being responsible: 9cf676c

Hi,

got the same error here. For the records, I fixed it by defining a method calling the @lower class or whatever it is :
def flush!
@lower.flush!
end

Hope this helps.
