The way to check the MachXO configuration status through JTAG is to use the capture instruction. For the MachXO the capture instruction (which is the instruction shifting out of the instruction register) is 0x19 (if the device is blank) or 0x1D (if ...
Description: MACHXO3D SDM Port INITN/DONE/PROGRAMN are dual purpose pins, which can be use as GPIO in user mode based on persistent mode settings. Solution: These are part of Feature Row settings and Feature Row bits that must be programmed to take ...
This information is available in the XP2 Family Data Sheet. How long it takes the XP2 FPGA to configure depends on the gate density of the device. The Data Sheet provides a table, called Flash Download Time, that describes the typical and maximum ...
The "Failed in Function VERIFY_SRAM_DONE_BIT" means that, the Diamond Programmer is unable to determine the statue of the DONE bit in the device's Status Register. This could have happened due to following reasons: The DONE bit is NOT SET due to the ...
The MachXO JTAG pins on the MACHXO Mini board share the same traces with some generic IOs of the MachXO device (as shown on page 4 and page 2 of the schematic). If the new design patterns have signals driving out of these pins, they could potentially ...
