For older distributions (Debian squeeze, Ubunutu Lucid, Maverick and Natty) backported packages are available in the ppa:paparazzi-uav/ppa. The loop creates six targets, with numbers attached, and makes their flash available on separate banks. Note: the register that tells OpenOCD the size of system flash incorrectly indicates 128kB so a value of 64kB is forced in the configuration file. I am trying to debug a bare metal application using openocd (seggers does not provide support for the cortex a-53 so jlink won't work). pl w temacie [OpenOCD][Olimex] STM32F100 nie komunikuje się poprzez JTAG Pobierz plik openOCD.

The scanning of designs is a very efficient way of improving their testability. OpenOCD also reports this message when you are trying to take control by JTAG and you already have it (the second reset sequence causes the JTAG to relinquish control, and the plug boots). OpenOCD has been able to succesfully access send something through the JTAG interface, and, even better, it has even been able to scan out device ID 0x44002093, which it understands to be a Xilinx device!
