BOOST-LP5569EVM: can't read program memory register correctly

user6519235

Part Number: BOOST-LP5569EVM
Other Parts Discussed in Thread: LP5569

Hello,

I made a simple pattern program using LP5569_EVM.
There is no problem with compile, load, upload, and Run program.
In this state, when I read the data written in programs _ mem _ 00 to 31 , even addresses are read as 1Dh, and odd addresses are read as FFh. Why is this?

I am looking for your reply.

Hi Hyodo,

Did you read the SRAM when run the engine?

And did all the returned data are read as FFh?

What about your 4Fh register(PROG_MEM_PAGE_SELECT) setting?

Best Regard

No, engine stopped and read.

Yes.(Please refer attached file)

After uploading, read data of R4Fh is 0Fh.

Changing to 00h, read data did not change the value. Please refer to the attached file.

What I really want to know is how to write .hex file data to LP 5569 PROGRAM _ MEM.

To do this, I am trying to read LP5569 from R50h to R6Fh to see how the loaded data is written.

Best regards,

Hyodo

Hi Frank,

I asked how to upload the procedure from host to LP5569.
But I got the log when I was [Upload to LP 5569] on the EVM board, so I solved it. Thank you.
