Hi,thanks for your reply.I just have no method to solve this problem. Those codesys errors do not appear everytime,means that the errors occured randomly .And when i changed the codesys's code and download to the board,this also may make the sceen black.When the screen is black,the same appearance of codesys is "ExceptionSysWindowSingleTask".Here i post the CODESYSControl.CFG file.
another picture of the codesys shows
hi, when i use codesys in linux system on I.mx6dl board,something wrong occured.I just change the task's run priority level and cycle time.After download application to board,the screen keeps black after i click run button.The codesys log which showed me is "ExceptionSysWindowSingleTask 0x2dff20 0x683bb150 0x7428a9a8". Runtime:3.5.15.20/3.5.16.20 IDE:CODESYS V3.5 SP16 Patch 2 + (64-bit)
