UmTRX firmware update

Hi all, If you use the latest UHD sources, you should update your ZPU firmware to the latest version: http://people.osmocom.org/ipse/umtrx-v2/fpga_bitsream/2013-06-25-2f3817a9/ You could update your FPGA image as well, but ZPU part is critical for the smooth operation with the latest host side code. If you don't update ZPU, all UHD utilities will exist on startup. The reason is that the new host code sends a command to ZPU which older ZPUs does not understand, so the host side code raises exception and exits. A new feature which is the reason for the breakage is that now you could not only set, but also read back the current value of the TCXO calibration DAC. If you run this utility without any parameters, it will autodetect UmTRX and read the DAC value from it. https://github.com/fairwaves/umtrx_scripts/blob/master/python_lib/umtrx_vcx… This is praticularly useful when you calibrate using GPS and want to store this value to EEPROM to use it when GPS is not available. -- Regards, Alexander Chemeris.
