I was also using a separate power supply for the module - not derived from USB - because the FT232 would take a while to power up, and the CSR module I had used a POR circuit (holds reset line low for ~3ms at power on) it would power up sometimes before, sometimes after the FT232. I cannot remember exactly how I managed to stop this but I believe it was playing around with the Vreg line (Vreg enable, also the 'multi-function button' input). The result of the shoddy config was - very slow reading with PStools, and then it froze.
It took me a few days of head-scratching and I actually had to order a second module to read the keys off (with PStool) and write them to the bricked module (also using PStools).
It can mean the chip gets stuck in a bootloop because whilst the firmware is in ROM, the on-board I2C EEPROM contains configuration for booting as well as user config. These chips are easily bricked by the 'CSR-tool' as it only writes specific keys- and wiping the rest. However we don't need those features for us to simply change the name.Electronics > Projects, Designs, and Technical Stuff NB: Some of the other changes that are possible with this software are only functional on a 32bit machine (ie win7).

Good luck!ġ) Sign up to the CSR website here (use the register link) Unfortunately the process documented below (done a couple of years ago) no longer works, clearly CSR or rather Qualcomm is not interested in supporting makers! Please do your own internet searches and you should be able to find old 'private' copies of BlueSuite.
