PGA900: PGA900 EVM can not load HEX file

Hi Hao Su,

What hex file did you try to load? Our PGA expert is on holiday break until after the new year, so this may take a little time to fully resolve.

Hi Tom:

The attached file is which I used . I also tried the hex file which was upload by Scott.

Could you tell me that is the same hex can be used both for OTP and DevRAM ?

thank you

Hi Huo Su,

I do not have any hardware available at the moment to verify your HEX file. This will be looked into once everyone is back from the Christmas/New Years break here in the US.

Hi Tom

About FW program of PGA900, I have two questions , May  you can help me.

1. Is  XDS200 necessary for program of PGA900? If I have built hex file , do I still need to connect XDS200 to EVM  board when I use GUI to load hex file?

2. Is there any other device can used for PGA900 FW program ? XDS200 is quite expensive and not very efficient for manufactory

Thank you for your support.

Hi Hao,

Scott will be back on the 4th and should be able to help you then.

Hi Hao,

Yes, the same hex file can be used for the DEVRAM or the OTP. The XDS200 is not necessary to program a built hex file to the PGA900-- it can be done with any of the digital interfaces (SPI, I2C, OWI). Any hardware that can communicate via the same digital interfaces as the PGA900 can be used to program the OTP.

As for the OTP not writing correctly, are you certain that the security lock has not been enabled? You can check the SECLOCK register, or the DEBUG_LOCK bit in the MICRO_INTERFACE_CONTROL register.

Hi Scott:

I try to load HEX to DEVRAM. But I found the rigisters don't change anything after load hex. SEC-LOCK and Debug-LOCK are disable. Could you help to check what is wrong with it? I have tried to use two EVM board .I can change rigister manually but can't by hex.

attached is hex.file, configuration after load hex and DEV RAM DATE

thank you

Hi Hao,

You have closed the J15 jumper, but can you please measure the voltage on that jumper when it is closed to confirm that it is at 7.5V? What is the voltage input to the PGA900EVM?

Regards,

Hi Scott:
I use 20v as input voltage for EVM board. I measured that voltage of J15 is 7.5V, the Avdd is 3.0v, Dvdd is 1.8V.
thanks for support

Hi Hao,

I will try loading the hex files that you have attached and I will get back to you by the end of the week.

Regards,
