Flash Programmer (ADAU145x)

Click here to return to the Master Control Port section.

This module provides support to write raw data to the external flash memory using I2C/SPI. The I2C/SPI write is performed during the initialization before the audio processing in the schematic is started.

Configurations

Click on the configure button to configure the SPI/I2C interface for the module.

GUI Control Name	Default Value	Range	Function Description
Protocol	SPI	SPI/I2C	Master Control Port Protocol
Bit Rate	100kHZ	100 kHZ - 100000 kHZ (for SPI)/ 400 or 800 or 1000 kHz (for I2C)	SPI/I2C Speed
Slave Select	0	0-6	Slave Select for the SPI. Register window should be configured to match this selection.Please refer the note below.
Sub-Address Bytes	2	1-4	Number of address bytes excluding the read/write command
PageSize	128KB	0-32MB	Page Size of Flash
SPI Mode	Mode 3	Mode0/Mode3	SPI operation mode
R/W (Chip Address) Bytes	1	0-255	Command Bytes (Number of bytes required for command)
Write Instruction (SPI)	2	0-255	Instruction value for a write operation (0x0 for ADI audio devices, typically 0x2 for eeprom/flash)
Read Instruction (SPI)	3	0-255	Instruction value for a read operation (0x1 for ADI audio devices, typically 0x3 for eeprom/flash)
Write-Enable instruction (SPI)	6	0-255	Instruction value for device write-enable operation
Block Protection Unlock (SPI)	152	0-255	Block Protection Unlock command for SPI falsh devices. This is an optional command. This can be disabled.
Chip-Erase instruction (SPI)	96	0-255	Instruction value for device erase operation
Chip-Erase Time (SPI)	5 sec	1-600 sec	Time required for chip erase operation
Block/Sector Ersae Insutruction (SPI)	216	0-255	Block/Sector erase command for SPI falsh devices. This is an optional command. This can be disabled.
Block/Sector Address to Ersae (SPI)	0	0-16777215	Block/Sector address to erase SPI falsh devices by block/section. This is an optional command. This can be disabled by disabling the Block/Sector Ersae Insutruction
Data File	NA	NA	Raw data to be written to the flash (Can be ascii text file/ binary files like wav file)
Data File Mode	ASCII	ASCII/Binary	Mode to write the file. Audio files like .wav should be written in binary mode
Configurable Address	Disabled	Enable/Disable	Enable/Disable the start address for each files
Start Address	0	0 - Maximum of FLASH/EEPROM Size in bytes(Increment by page size)	Write the data in the flash/e2prom from the specified address

Any change in these SPI/I2C configuration parameters requires a recompilation.

Writing Multiple Files

Number of files to be written can be configured by right clicking on the module. All the files will be written one after another if multiple files are selected. This support upto 32 files.

Example

Writing a Wav file to SPI EEPROM using Flash Programmer (ADAU1452)

Add Flash Programmer module to the schematic.
Configure SPI parameters in the Control Port Properties window. (Below window shows SPI configuration required to write to EEPROM in EVAL-ADAU1452MINIZ board)

Select Binary mode
Select the Wav file to be written (Make sure size of the wav file is not greater than the size of EEPROM. In the case of EVAL-ADAU1452MINIZ, size of wav file should not be greater than 128 KB)
Press OK. Then Link compile download.
Press OK when the following warning displayed.
