Dear Sir,
We are facing one problem,Reason is ERASING data of programmed device.Actually After downloading the S19 file into the device we are checking the unit is working properly or not  as per specification.Then after sending to customer place some of the units which are not working are coming back for analysis.So after analysis we checked Hardware,We found that no out put from device.So i read the device.It is totally Blank.We surprised All Units are working ok before sending in my company,then how the data is corrupted? We are not understanding How the device data is erased.
Please tell me what are the reasons for data corruption,so that we can modify out H/w & S/w,
Thanks in advance
