New ContributorMAX5 CFM access?
Frequent ContributorHi there,
In MAX series device, you cannot control CFM like EPCQ in other device, because CFM is an internal Flash. According to your description, I think the function of real-time ISP can help u. Please refer such link and we can discuss the details.

New ContributorThanks for the very quick reply.
given your information, I'll need to control the JTAG pins (from an external source, we got a microcontroller which could receive the image via ethernet and then send it via JTAG) to remotely program the MAX5 (we are looking for a solution to apply an update for devices once they are shipped / where we cannot connect a JTAG probe / byte blaster anymore).
I believe this got easier in MAX10 devices, correct?
Kind regards,

Hi there,
That is correct, because in MAX10, it can use the On-Chip Flash Intel® FPGA IP Core and do Remote system upgrade. Here is two link of example design for MAX10's RSU, one is for uart, the other is for I2C.

Since changing to MAX10 would need a complete redesign of our PCB I'll try to focus on a solution using the existing MAX5 design.
I found some valuable information about JTAG here:
1.7.2. Steps to Port the Jam STAPL Byte-Code Player (intel.com)
So from what I can grasp, the steps would be:
Convert MAX5 .pof file to .jbc
Transfer .jbc file to our microcontroller which has a direct connection (via GPIO) to the MAX5 JTAG pins
Use the Jam STAPL Byte-Code Player (C code / library) to program the MAX5
Are there any additional steps I missed?
Kind regards,
Felix
