Max10 remote update bitstream

[fogl]

Hello everybody,

I would like to remotely update the Max10 bitstream written in internal flash CFM region. I am not sure how can I generate a proper bitstream.

I thought the .pof file can be used for that. I compared the bitstream written in flash to .pof file used for programming and i noticed there is no direct match (i am aware of .pof file header/footer).

I tried to generate the .rbf file, but acoding to information it is not possible for the Max10 devices: https://community.intel.com/t5/Programmable-Devices/rbf-file-for-MAX10-to-use-JRunner/m-p/127064

How can i generate a proper bitstream that can be used to configure the CFM region remotely using the On-Chip Flash IP Core?

Hi,

Thank you for contacting Intel community.

You can refer to AN 741 below for Remote system update for MAX10.

Thank you for your reply, I managed to generate the .rpd file with Internal Configuration Mode Option.

It generated the output_file_cfm0_auto.rpd.

Now I compared the content of this file (output_file_cfm0_auto.rpd) to the data of the same project (same .pof file) written to flash using the jtag cable. I am using On-chip Flash IP to read the data. The data is not the same. Is this expected, I was expecting the same data?

Hi,

The data should not be the same. As POF has header while RBF do not have header.

I am comparing the data written in the internal flash to .rbf file. Is the header of the .pof file also written to the flash during the programming phase - i assume not?

Hi,

The answer is, yes, you will see different data. The header of the POF file also written to the flash during the programming.
