Hi, Currently I face a problem in the Lbs command, it appears that some times it works correctly and some times not, the Data catch option is turned off and I suspect that it is connected to Lbs command. I am going over the or1200_define, also I saw in the mem2reg file the problem appears when addr = 2 it get the wrong value form dcpu_dat_i that comes from qmem. You can see clearly that in case of lbs r3, 0x0(r12), in the rf file the r12 has the correct value but the value of the content of addr r12 doesn't go to r3, the contents get inside the risc through rdm and you can see it after manipulation in mem_data of mem2reg file. Can you help? Thanks in advance, Shiri Schnapp SmartLink LTD -------------- next part -------------- An HTML attachment was scrubbed...
