See below for steps on how to perform Dual-Boot in MachXO5-NX Background: The current implementation of Dual-Boot is that the JUMP table is found at Address 0. We are changing the implementation of Dual-Boot as below. For this new implementation, the ...
To access the MachXO5-NX Development Board via SSPI using the onboard FTDI, the user should follow the steps as described below. 1.) The MachXO5-NX Development Board Setup is shown below. Notes: * The device is in configuration mode * JP1 and JP9 is ...
Description: Erase, Program, Verify Quad 1 enables that QE bit to '1'. In general, there are two (2) requirements/steps to enable booting from external SPI Flash through x4 (QUAD Mode) Step 1 - Convert the bitstream file into hex (Quad I/O read mode) ...
See below steps to significantly improve the boot/configuration time from internal flash: 1.) In your source project, generate a bitstream that contains the following: * Set the FLASH_CLK_FREQ = 112.5MHz * Set CONFIG_IOSLEW = FAST 2.) *Launch the ...
Assuming the frequency of the SPI Flash is not the limiting factor, there are two factors affecting CCLK frequency setting of Lattice ECP2M device in SPI Flash configuration mode: 1. fMAXSPI This is the maximum frequency that the internal ...
