This section describes the
Memory Functions
settings available when using devices. Memory
functions include OTP, QSPI or OQSPI flash memory programming.
7.2.7.1
OTP Memory
Figure 65: OTP Memory
This test enables the OTP memory programming.
describes the available options for the
OTP Memory
image write operation.
Note:
If the binary is larger than the available OTP image area (OTP memory excluding the header area), the
PLT software will split the binary into two parts. The first part will contain only the OTP image area. The second
part will contain the OTP header fields, split in OTP words. PLT will burn the non-zero words one by one, as
single OTP entries in the OTP header area. The check empty feature will handle the first part as an OTP image
binary. The second part will be checked word by word.

Skip if written
Memory protection options:
No check:
No protection is enabled. PLT will attempt to burn the OTP memory
without running any check.
Check empty:
PLT will first check if the OTP memory to be burned is empty. If it is
empty will burn it.
Check if data match:
PLT will first check if the memory to be burned is empty. If it is
not, it will compare the contents with the data to be burned. If the data are not the
same the test will fail without making any changes to the memory. If the data are the
same, PLT will not burn the memory and continue without error.
Skip if written:
PLT will read the contents of OTP memory. If it contains any data, it
will skip writing without producing any error.
Verify image
If this option is enabled, PLT will read back the contents of the OTP memory and
compare them to the original image file. If these do not match it will fail.
Image path
Via this field, the user specifies the binary file to be burned into the OTP. A
.bin
binary file of any name can be selected.
