Why does Intel® Quartus® Prime Programmer fail to program an Intel® MAX® 10 device with JTAG Secure mode enabled in a device chain? - Why does Intel® Quartus® Prime Programmer fail to program an Intel® MAX® 10 device with JTAG Secure mode enabled in a device chain? Description You will observe Intel® Quartus® Prime Programmer failure when you have an Intel® MAX® 10 device with JTAG Secure mode enabled in multiple device JTAG chain. Resolution To work around this issue, perform Intel® Quartus® Prime Programmer programming separately between the Intel® MAX® 10 device with JTAG Secure mode enabled and the rest of the devices in the JTAG chain. - When you are programming an Intel® MAX® 10 device with JTAG Secure mode enabled, you need to bypass the rest of the devices in the JTAG chain - When you are programming the rest of the devices in the JTAG chain then you need to bypass the Intel® MAX® 10 devices with JTAG Secure mode enabled. This problem is fixed starting with the Intel® Quartus® Prime Software version 21.1.
