[Verification successful] eZ-FET Lite 5528

Flashing steps (also the steps to restore the launchpad’s onboard ezfet firmware):

STEP1:

    Find a programmer that can program 5528. The Ez-FET or FET430UIF on the launchpad can be used. Connect it to the target board according to the logo.

STEP2:

Install the UniFlash tool     on your computer and download  the resource package of Ez-FET lite

STEP3:

    Unzip the resource package, find the firmware file eZ-FET lite rev 1.10 Release PackageFirmwareEZFET_LITE_Rev1_1_BSL_1_1.txt , and copy it

STEP4:

    Open UniFlash and select the MSP430F5528 chip and connector. Just select the first connector by default.

STEP5:

Find the Erase column     on the Settings & Utilities page , click Mass Erase , and wait for the erasure to complete.

STEP6:

Check Allow Read/Write/Erase access to BSL memory in the Download column     above and return to the Program page

STEP7:

Select the firmware you just copied in     Flash Image(s) , click Load Image to upload the firmware, and wait for the prompt that the upload is successful.

STEP8:

    Unplug the programming cable and plug the target board directly into the computer. The computer will make a sound prompting you to insert a new device, but you can't see it in the device manager. Don't panic.

    Open CCS or Energia ( IAR has not tested it), choose a program to upload, you will be prompted to update the firmware, just select update ( Energia will automatically update), after the update, the computer will be able to see the two serial devices.

STEP End:

    The burner I had burned on hand has been taken away by someone, so this tutorial is written from memory. There may be some missing steps in it, such as installing the driver.

    If the above steps are unsuccessful, you are welcome to find me for online matching. The purpose is to make everyone successful.

    I was stuck for nearly two months, and finally found out it was a driver problem and my head hurt.

I lost my temper during the Chinese Valentine's Day and stayed away for two days

I adjusted the ink screen and wrote the program using energia on the main computer. As a result, the firmware was automatically updated and all the ez-fets on the 5529 and 5994 development boards were bricked.

have no choice

After searching the internal and external websites, I tried to treat a dead horse as a live doctor. I tried it all afternoon and all night, but it still didn't work.

Back home... a success

Probably a driver issue

Update tomorrow

All the components are pasted, and the firmware can be burned into it. The task manager can also see the two COM ports, but it cannot be burned into the target board. It reports that the vcc setting failed and the device cannot be found.

I made an official board and on the way to see if there is something wrong with the 5528 I bought or the pcb drawing.

The capacitances of several capacitors on the board were copied incorrectly and have been corrected.

Streamlined official design is a Band-Aid component, which has not been verified.
