Firmware Rewrite Limit?

Now that there is custom DVB-S/S2 firmware available for the LimeSDR Mini, I am considering releasing a version of the Portsdown TV Transmitting software that can switch between the stock firmware and the custom firmware (which enables higher symbol rates to be encoded on the FPGA).

Before I do this, I need to know if there is a limit (like there would be on an older EEPROM) as to how many times the firmware can be reflashed before manufacturer does not guarantee firmware retention. I would guess that there are 2 parts to this question - the firmware and the gateware?

So, can we flash back and forth without concern or is there a limit of, say 1000 flashes?

Hi @DaveG8GKQ,

As far as I can see you are using LimeSDR-Mini, hence Intel MAX10 device. According to this, endurance counts to at least 10,000 program/erase cycles.

For LimeSDR-Mini firmware is encapsulated to gateware, hence the same.

Thanks @Zack

Just the answer that I wanted. Twice a day for about 15 years. That should be OK!!
