15 years agoI generally agree. A special point is, that BeMicro has been designed by Hitex, using a form factor they had introduced for other evaluation boards (e.g. NXP ARM) before. I don't know, if it's an Altera contract development at all.
The I/O connector mapping is completely documented in the BeMicro manual, for the FT2232 connection I have posted my findings in another thread: http://www.alteraforum.com/forum/showthread.php?t=20490 In addition, here are the FT2232 connectionsAD0 TCK
AD1 TDI
AD2 TDO
AD3 TMS
AD4 NCONFIG
AD5 NSTATUS
AD6 CONF_DONE
AC0 4052 Sel A
AC1 4052 Sel B The 4052 is multiplexing the FT2232 JTAG pins according to Sel A/B as follows: 0 1 2 3
TMS NC IO NC R404/TMS
TDO NC IO NC R406/TDO
TDI NC IO DATA R403/TDI
TCK NC IO R402/DCLK R401/TCK I didn't have a need to trace the FPGA I/O pins connected in Select 1 mode. Select 3 is the default mode used for JTAG configuration.
