Hi, sorry for bumping an old thread, but I am tinkering my BM54 for two days now, and still out of luck flashing 29f400 . I managed to connect C161 to TTL serial adapter and processor was detected by FLASHit, then I successfully made a flash dump and tried to flash new firmware back, but got time-out error



So far tried: +12V on RST, different baud-rates in FLASHit, all "Target reset" configuration possible, flashing from other computer and then from Windows XP 32bit virtual machine. Any thoughts?

P.S. I will try to get my hands on Willem Programmer this Wednesday, hope it will comes with PSOP44 adapter.
Also, while searching the internet on this problem I got some info on making Line-out's, Aux-in and stock Amps upgrade (with TDA7375 or TDA1557Q).
I also found firmware from this units:
