PyOCD v0.35.1 及 v0.36.0 的 RTT 存在一个 Bug 导致使用 RTT 是出现 “C Control block not found [__main__]” 错误。回退到 v0.34.3 则该问题消失，参见 [Control block not found when using rtt with pyocd 0.35.0 #1553 ](https://github.com/pyocd/pyOCD/issues/1553)
遇到该问题可以使用 [Reset the offset in finding control block #1654](https://github.com/pyocd/pyOCD/pull/1654/commits/94debabb9f8b4415fa1f5ede409e77b6f60f6375) 或 [Fix RTT Control Block Search #1669](https://github.com/pyocd/pyOCD/pull/1669/commits/4c9acbcefb58de87d6e164e1868cd1cee2c16f31) 方法临时修正。但目前这两种修复方法都不支持指定 --address 和 --size 参数，因此，即便使用了这两个 pack，但在使用 RTT 时指定了这两个参数，依然会报“C Control block not found [__main__]” 错误。
