Can I retain the contents of User Flash Memory while programming an Intel® MAX® 10 device? - Can I retain the contents of User Flash Memory while programming an Intel® MAX® 10 device? Description Yes, the contents of User Flash Memory (UFM) in Intel® MAX® 10 FPGAs can retained in certain use cases. When you see the below message in the Intel® Quartus® Prime Standard software while programming an Intel MAX 10 FPGA, Quartus Programmer erases the CFM as well as UFM content. Warning (16139): Perform full chip erase and program at device index 1 The Programmer issues a full chip erase if the ICB bits of the new pof file does not match with the ICB bits of the previously programmed pof file. Resolution To avoid a full chip erase of the Intel MAX 10 flash memory and to retain the UFM content: Ensure a factory default image exists in CFM0. Program CFM1 with the application image. Use Dual Configuration IP or CONFIG_SEL pin to switch between images or boot from CFM0 and CFM1. This requires the design to have Configuration mode selected as Dual Compressed Images Verify Protect feature must not be enabled when trying to retain the UFM contents while programming.
