PGA900EVM: How to OTP PGA900 by PGA900EVM in CCS or PGA900GUI

Part Number: PGA900EVM

Hi, now I have debugged my pga900 code in CCS. I want to download my code in pga900 and weld pga900 on my own board.

What software can I use to do this thing?In CCS,it seems just can debug my code but can not download.

In PGA900 GUI there is some thing i can do with OTP,but seems just can check OTP memory.

So, my quession is how can I download my pga900.hex or pga900.out to my pga900 and use my pga900 on my own pcb not only in PGA900EVM.

Please tell me more specific detail about OTP. I see it can OTP programming by SPI and IIC in PGA900 datasheet,but i still don't know how to do it

I checked E2E i know some details like use jumper(J15) on EVM  to apply the output of the onboard 7.5V regulator to the VP_OTP pin.And someother questions mentioned to use Uniflash to OTP pga900 code,but I still don't know how to do it in details.

I am a greenhand of PGA900 and CCS, so could you tell me the method as detailed as possible.

Thanks a lot,best regards.

    Hello,

    The simplest way to program the OTP is through the EVM GUI. You have already mentioned the J15 jumper, which should be shorted to connect 7.5V to the VP_OTP pin. Next, you will need a hex file of your firmware. In the EVM GUI on the OTP programming panel (from the screenshot you posted), you click on the file folder next to the "Hex file path" field, and browse to the location of your hex file. Once your hex file is selected, you click "Load OTP Memory" which begins the OTP loading procedure. Note that you must already be in digital interface mode, with the M0 in reset before starting the OTP loading procedure. The OTP status bar will update based on the progress of the loading. Once the loading is complete, you can click "Verify OTP" to check that it was successful. This will check the contents of the OTP against the hex file that you have selected. If the data matches, the light to the right of the OTP status bar will turn green.


    Regards,
