I was checking eBay and saw many USB to RS232 adapters for abour 15-20$. Can any of these used with the Guruplug to get the serial console? If so it will be much cheaper than getting it from Globalscale.

Hi,

these should work for getting access to the terminal, given that they can handle 3.3 V levels (which the FT232BM/BL do) but not for programming the flash via JTAG.
Actually the GuruPlug JTAG board has two functions: a) console access and b) JTAG for flashing new firmware / bootloader.

Regards,
Oliver

Oh ok. Thanks for the info! I didn't think about the programming part! Tongue
