Tool/software:
Hi,
According to AWR2944 EVM hardware design, we design our own board and AWR2944 EVM as belows:
By road test, we compare our board and AWR2944 EVM board. We find two main poblems for our custom board. one is more noisy points are introduced, the other one is system halted fault .
For the first problem, more noisy points, we think may be two factors, one is the manufacturing process of antenna,the other is the location of antenna.Though the hardware designs are identical, because of the different manufacture and different board material, that lead to different performances, is that right?What parameters or factors will affect antenna performance? By comparing the two boards we can see that:the antenna location of our own board is in the middle of the board, while in the AWR2944 EVM, the antenna loaction is in the left of the board. will more noisy points be introduced for different antenna location?
For the second problem, system halted, we thinks that more noisy points make the system into unknow status and resulted in system halted .The other reason is power chip, our power chip is ST2636，the AWR2944EVM‘s is LM63635DQDRRRQ1.Different power chips will lead to sysytem halted problem,is that right?
