Hello Alex, Sorry, the early thread was close, so I need raise a new one. Very glad to heard latest firmware support A53/72.... But I tried, still failed. jlink.exe show "Could not measure total IR len. TDO is constant high." There is one thing I don't understand, by your early reply the RTCK is important for ARM7/9.
