Assembler workflow (without HEX file working)

[douggilliland]

Here's how I make the HEX file without HEX file output working from the assembler

• Create assembler source
• Run assembler to create assembly opcodes listing
• Use In-System Memory Content Editor
• Connect to card
• Select Hardware
• Scan Chain - loads current Instruction ROM from the target
• Click in the data area
• Manually type in the assembly opcode values
• Edit to save as .HEX file
• Run MegaWizard Plug in Manager by double clicking on the BlockROM_Instrucyion:Instr_ROM in Quarts Entity window
• First Screen:
• Entity is ROM: 1-PORT
• 32-bits wide
• 256 words of memory (minimum)
• Auto Block Type
• Single clock
• Second Screen:
• Unclick q output port
• All registered ports controlled by enable(s)
• Unclick 'aclr'
• Unclick 'rden'
• Third Screen:
• Yes, use this file
• Set to the HEX file that was exported
• Allow In-System Memory Content Editor ro update content (will imply a dual port with the second port connected to the In-System Memory Content Editor.
• Can then later import the HEX file from the In-System Memory Content Editor (Edit - Import Data From File)

Flow with HEX output working should be:

• Create assembler source
• Run assembler to create assembly opcodes listing
• Run MegaWizard Plug in Manager by double clicking on the BlockROM_Instrucyion:Instr_ROM in Quarts Entity window
• First Screen:
• Entity is ROM: 1-PORT
• 32-bits wide
• 256 words of memory (minimum)
• Auto Block Type
• Single clock
• Second Screen:
• Unclick q output port
• All registered ports controlled by enable(s)
• Unclick 'aclr'
• Unclick 'rden'
• Third Screen:
• Yes, use this file
• Set to the HEX file that was exported
• Recompile FPGA with the new assembly code

Can also load the HEX file from the In-System Memory Content Editor using Edit, Import File pulldown.

HEX works now. Fixed code import by putting it in a different place in the source ree.
