+Setup for testing:
+=================
+
+* TUMPA or equivalent dongles supported by OpenOCD. https://www.diygadget.com/JTAG-cables-and-microcontroller-programmers/tiao-usb-multi-protocol-adapter-JTAG-spi-i2c-serial
+* Tag-Connect cable appropriate to the board such as TC2050-IDC-NL https://www.tag-connect.com/product/tc2050-arm2010-arm-20-pin-to-tc2050-adapter
+* Tag-Connect to ARM20 adapter https://www.tag-connect.com/product/tc2050-arm2010-arm-20-pin-to-tc2050-adapter
+
+
+
+WARNING: There is no point in getting the retainer clips https://www.tag-connect.com/product/tc2050-clip-3pack-retaining-clip since it wont fit in, you have to hold it.

+
+S/w baseline:
+
+openocd : master branch 04154af5d6cd jtag: linuxgpiod: drop extra parenthesis
