I have a USB to Serial breakout which has CP2102 and MAX232 chips on it. I wrote a program in Keil and generated the Hex File. How do I flash this hex file onto the AT89C51 (which is also another board with all the capacitors,resistors and crystal oscillator, everything is there) using the USB to Serial breakout? Flash Magic works only for philips chips, what is the alternative to ATmel chips?

The AT89C51 chip should contain an embedded USB boot loader pre-loaded on the chip. The boot loader is used to program the flash. The USB Boot-loader is described in this document.

The USB Boot-Loader works with the Atmel FLIP software. The FLIP software is available for free from the Atmel website.

.TH DFU-PROGRAMMER 1 'May 28, 2014' 'DFU-PROGRAMMER' '

.SH NAME

dfu-programmer - USB firmware upgrading for Atmel microcontrollers

.nh

.SH SYNOPSIS

.Bdfu-programmer

target[:usb-bus,usb-addr] command [options] [parameters]

.br

.Bdfu-programmer

--help

.br

.Bdfu-programmer

--targets

.br

.Bdfu-programmer

--version

.SH DESCRIPTION

.Bdfu-programmer

is a multi-platform command line Device Firmware Upgrade (DFU) based programmer

for the flash memory on Atmel AVR, AVR32, XMEGA and 8051 based microcontrollers

which ship with a USB boot loader.

It supports In System Programming (ISP) for developers and potentially

product updates in the field.

Those boot loaders are patterned after the standard USB DFU 1.0 class

specification, but depend on extensions defined by Atmel to the extent

that standard DFU drivers will not work.

.PP

To use it, first connect the device to be programmed and ensure that it

comes up in DFU mode.

The microcontrollers come up in that mode as shipped by Atmel;

or they may reenter that mode after a special hardware reset.

Then invoke this program to issue one or more DFU commands.

You will normally need to start by issuing the 'erase' command;

the default security policies prevent extracting firmware, to prevent

reverse engineering of what is usually proprietary code.

.SH USAGE

There are no mechanisms to implement gang programming.

By default, the first device that matches the id codes for the

given target is selected. Many targets share the same id codes.

Accordingly, you will usually avoid connecting more than one

device of a given family (AVR, XMEGA, AVR32 or 8051) at a time.

.PP

The target may be qualified with the USB bus and address number

of the device you wish to program. This allows programming multiple

devices of the same family at the same time.

.PP

All of these commands support the 'global options'.

Unless you override it,

commands which write to the microcontroller will perform

a validation step that rereads the data which was written,

compares it to the expected result, and reports any errors.

.PP

Note that unlike Atmel's BatchISP program, dfu-programmer will

only perform a single operation at a time. Erasing and programming

require separate commands.

.HP

.Bconfigure

[--suppress-validation]

data

.br

Bootloaders for 8051 based controllers support writing certain

configuration bytes.

.HP

.Bdump

[--force]

[--bin]

[(flash) --user --eeprom]

.br

Reads the program memory in flash and output non-blank pages in ihex format

to stdout. Use --force to output the entire memory and --bin for binary

output. User page and eeprom are selected using --user and --eeprom.

.HP

.Berase

[--force]

.br

Erases all the flash memory. For AT90 and ATmega type devices a

chip erase must be performed before other commands become available.

Erase first checks if the memory is blank unless --force flag is set.

.HP

.Bflash

[--force]

[(flash) --user --eeprom]

[--suppress-validation]

[--suppress-bootloader-mem]

[--serial=hexbytes:offset]

file or STDIN

.br

Writes flash memory. The input file (or stdin) must use the 'ihex' file

format convention for a memory image. --suppress-bootloader-mem

ignores any data written to the bootloader memory space when flashing

the device. This option is particularly useful for the AVR32 chips.

The --force flag tells the program to ignore whether memory inside

the program region is blank.

User page and eeprom are selected using --user and --eeprom.

The user space flash on AVR32 chips lies outside of the normal range

of flash blocks and is designed to contain configuration parameters.

Bootloader configuration uses the last 4 to 8 bytes of the user page.

If this data is corrupted, the device will restart into the

bootloader until valid data is used (see atmel doc7745 or doc32166).

--force is always required here.

.PP

--serial provides a way to inject a serial number or other unique

sequence of bytes into the memory image programmed into the

device. This allows using a single .ihex file to program multiple

devices, and still give each device its own unique serial number. For

example, --serial=ABCDEF01:0x6000 would program the byte at 0x6000

with the hex value AB, the byte at 0x6001 with the value CD, and so

on. There must be an even number of hex digits, but the sequence can

be any length. The offset is assumed to be given in hex if it starts

with a '0x' prefix, octal if it begins with a '0', otherwise is it

assumed to be decimal.

.HP

.Bsetsecure

.br

Sets the security bit on AVR32 chips. This prevents the content being

read back from the chip, except in the same session in which it was

programmed. When the security fuse is set, almost nothing will work

without first executing the erase command. The only way to clear the

security fuse once set is to use a JTAG chip erase, which will also

erase the bootloader.

.HP

.Bget

.br

Displays various product identifier bytes.

.HP

.Blaunch

[--no-reset]

.br

Launch the application by resetting the device. The --no-reset flag

can be used to launch the device without a reset (jump to the start

address of the program).

.SS Global Options

--quiet - minimizes the output

--debug level - enables verbose output at the specified level

.SS Configure Registers

The standard bootloader for 8051 based chips supports writing

data bytes which are not relevant for the AVR based chips.

.LP

BSB - boot status byte

.br

SBV - software boot vector

.br

SSB - software security byte

.br

EB - extra byte

.br

HSB - hardware security byte

.SS Get Register

bootloader-version - currently flashed bootloader version

.br

ID1 - device boot identification 1

.br

ID2 - device boot identification 2

.br

manufacturer - the hardware manufacturer code

.br

family - the product family code

.br

product-name - the product name

.br

product-revision - the product revision

.br

HSB - same as the configure_register version

.br

BSB - same as the configure_register version

.br

SBV - same as the configure_register version

.br

SSB - same as the configure_register version

.br

EB - same as the configure_register version

.SH BUGS

None known.

.SH KNOWN ISSUES

The at90usb series chips do not make available any read/write protect

flags so the

.Bdump

.Bflash

command may fail with a less than helpful error message.

.PP

To remove

.Bany

write or read protection from any chips, a full chip erasure is required.

For AVR32 chips an erase operation over USB will remove protection until the

device is rebooted. To remove the protection more permanently requires a

JTAG erase (which will also erase the bootloader).

.PP

You may need to be a member of the

.Buucp

group in order to have access to the device without needing to be root.
