4 Online Burning Operating Mode
All of the mentioned off-line burners are commonly used in mass production mode and it is very efficient to
meet mass production needs for specified files (fixed burning contents). However, in mass production, the
content of each burn will be changed, such as adding some specific information based on the Hex burn, and
then downloading it to the writer for burning. In this case, the offline production mode is not flexible enough. To
fullfill this requirement, it is necessary to use the online burning mode.
Online burning mode is set up as follow: the host computer (generally the PC or industrial computer)
connected to the offline burning device through USB data cable (host computer will identify it as HID device),
and then the writer connects to the burning target.
Figure 15. Online burning constrcution
The burning starts when the upper machine sends out the calling command (writerconfig.exe) and then users
can perform the needed operations on the upper system, such as adding specific content to the Hex file. For
the upper system, the offline burner in this mode is the device for performing burning. The upper system only
needs to generate different Hex files according to the user's needs and send the files offline to the offline
burner through USB data.
Table 13. Parameter list of online operating commands
Parameter
Function
Description
-ram
Writer RAM operation mode
Affirmative option
-otp
Writer operation OTP
Affirmative option
-burn
Execute burning
-f <hex file>
OTP target to be burned in Hex
file
-fast
Download speedup (only shorten
the time from the host computer to
the burner)
-p <txt file>
EEPROM target to be burned in
txt file
-poweron
Power on the target burning chip
Operating separately
，
which makes it convenient for the upper
system to carry out the power supply control on the target chip
when the function test is needed after burning.
-poweroff
Power off the target burning chip
-uuid
Achieve the 32-bit UUID on the
burning target chip
Operating separately, and must be used before burning the
OTP program, because after burning the OTP, the chip is
encrypted, and the UUID can no longer be read through the
interface
