JTAG Connection problem in custom BF561 board

Hello,

I am using BF561 custom board. I am working in Bmode 01 i.e. boot form 16 bit flash. Now with this mode I am not able to connect the JTAG with the board. JTAG test in the configurator is passing. I have connected flash, SDRAMs (as per EZ KitLite board of BF561 rev2.3). Now when I select Bmode 10 then I am able to connect the JTAG with board. But with this if do some LED blinking program etc. then it worked but if I tried to access SDRAM or any external device through code then JTAG disconnects. What may be the possible reason of JTAG not connecting in Bmode01 switch select.

 

Thanks

 

Deepak
