Item	Description
Select Device and Tool:
• Family	filters devices by family or recently used
• Device	specifies the device; click Apply to select
• Memory Model	This field displays only if the selected device has partitions. Select “Single Partition” or “Dual Partition” as applicable.
• Tool	specified the tool; click Connect or Disconnect as appropriate
Results:
• CP=OFF Checksum	This field displays only if enabled in Advanced Mode. Displays the imported hex checksum as if code protect is off for the device with current memory contents; value can be copied using CTRL+C.
• Checksum	checksum value for the device with current memory contents; value can be copied using CTRL+C. The 32 button toggles between Checksum or CRC32. See “Checksums” for more information.
• Pass Count	details the number of programming operations that passed
• Fail Count	details the number of programming operations that failed
• Total Count	the total number of programming operations
Command Buttons:
• Program	programs the device
• Erase	erases the device
• Read	reads the device
• Verify	performs a verify operation on the device
• Blank Check	checks whether the device is blank
Other:
Hex File	the Hex file location, Browse to locate the file
SQTP	the SQTP file location, Browse to locate the file
Output Tab	display of output data. Right-click in the Output window to access additional options.
Tool Tab	display of specific tool data, i.e., PM3, ICD 4, PICkit 4

 

Checksums

Note: Checksums may not be stable when they are still under beta (yellow) support.

Also see the section “How Do i Stop My Project’s Checksum from Changing?” in the “How-To’s” chapter of your MPLAB XC C Compiler User’s guide.

About CRC32 Checksums

For new devices, CRC32 checksums will be provided upon file import. For legacy devices, nothing will change.

There will no longer be “read” checksums for the new devices. You will need to perform a separate “Verify” to verify the code.

For new devices, MPLAB X IDE and MPLAB IPE run a 32-bit CRC calculation on the entire hex file to find its checksum. The checksum uses the standard CRC32 algorithm with the polynomial 0x4C11DB7:

(x32 + x26+ x23 + x22 + x16 + x12 + x11 + x10 + x8 + x7 + x5 + x4 + x2 + x + 1)
