TMS320F28027: Arm-based microcontrollers forum

Part Number: TMS320F28027
Other Parts Discussed in Thread: UNIFLASH,

hi there,

I have some questions about verify the flash content in Uniflash

I have 2 TMS320F28027 micros and flashed same firmware using xds200 via jtag, one micro's bootloader is all 0xff and another one 's bootloader is good, but both of them can verify successful in Uniflash GUI, so I'm wondering what does the verify function check

I also noticed that the Uniflash GUI has the calculate checksum function, there are 2 checksums, OTP checksum and flash checksum, after click the button, the OTP checksums are same but the flash checksum are different, what does the 2 checksum check and what's the difference between them

See the below link for the types of verification available:

Note that the default verification on all devices with the exception of MSP430 is "fast".

thanks Ki, I'm wondering is there a way that can verify if the entire flash memory of TMS320F28027 is match with the firmware file in Uniflash

best,

Not from the GUI. Verification is fixed to "fast".

But you can specify full verification using UniFlash CLI with the option: -s VerifyAfterProgramLoad="Full verification"

Thanks
