   I got a custom board based on MCIMX6Q6AVT10AE,now I attempt to test the ddr performance with 'ddr_stress_tester_jtag_v2.90'(for some reasons USB OTG did not work) , the cpu core starts to work after downloading the elf file into Ocram ,but the serail port txd Baud rate is 5760(not 115200), I can receive the data correctly with my serial port assistant tools,but CPU responses nothing to my command.I check  the signal with my oscilloscope and rxd data is all ok.How is this happening?Does the ddr_stress_tester_jtag_v2.90 tool set default Baud rate to 115200 ,or not?
