Usage

begin_memory_edit -device_name <device name> -hardware_name <hardware name>

Options

-device_name <device name>: Name of the device that holds the editable memory instances

-hardware_name <hardware name>: Name of the hardware that connects to the JTAG chain

Description

Start the memory editing sequence. The editing sequence should be terminated with end_memory_edit.

The sequence does not have to be terminated unless the device configuration is changed or a different

device is edited.

The hardware and device name can be obtained with the get_hardware_names and get_device_names

commands from the jtag package.

Example

# Instance 0 is configured as {0 1024 8 RW ROM/RAM mem0}

# Initiate a editing sequence

begin_memory_edit -hardware_name "USB-Blaster \[USB-0\]" -device_name \

"@1: EP1S25/_HARDCOPY_FPGA_PROTOTYPE (0x020030DD)"

# Write memory content using binary string

write_content_to_memory -instance_index 0 -start_address 575 -word_count \

2 -content "0000001011011100"

# Read back memory content in binary string written

puts \

[read_content_from_memory -instance_index 0 -start_address 575 \

-word_count 2 ]

# Write memory content using hexadecimal string

write_content_to_memory -instance_index 0 -start_address 575 -word_count \

2 -content "E2F1" -content_in_hex
