Abstract

A method of operation of a device programming system includes: providing a target programmer, having a programming bus; coupling an electronic device, having a non-volatile memory, to the target programmer by the programming bus; and programming a data image into the non-volatile memory by the target programmer includes: subscribing to a broadcast message, receiving a logical block, of the data image, by the broadcast message for programming the non-volatile memory, and sending an unsubscribe message after receiving the logical blocks of the data image from the broadcast message.

Claims

1. A method of operation of a device programming system comprising:

coupling a plurality of electronic devices, each having a non-volatile memory, to a target programmer of a flash memory programming system by a programming bus;

coupling a host server to the target programmer; and

programming a data image into the non-volatile memory of each of the electronic devices asynchronously using the target programmer including;

subscribing to a broadcast message of a programming stream of the data image at a mid-stream logical block address with the programming stream already started,

receiving a logical block of the data image by the broadcast message in a data buffer in the target programmer for programming the non-volatile memory,

copying the logical block concurrently into the non-volatile memory of the plurality of the electronic devices,

verifying the content of the non-volatile memory by comparing the non-volatile memory to the data buffer,

sending an unsubscribe message from the target programmer to the host server after detecting a logical block address wrap with a logical address of the logical block repeating the mid-stream logical block address, the unsubscribe message having a list of missing buffers for the data image, and

receiving the missing buffers for the target programmer in a sequence based on the unsubscribe message.

2. The method as claimed in claim 1 wherein providing the target programmer includes providing a first target programmer and a second target programmer.

3. The method as claimed in claim 1 wherein providing the data buffer in the target programmer for receiving the logical block from the broadcast message.

4. The method as claimed in claim 1 further comprising initializing a logical block address map in the target programmer.

5. The method as claimed in claim 1 wherein receiving the logical block includes receiving a mid-stream logical block.

6. A method of operation of a device programming system comprising:

coupling a host server to a target programmer;

coupling a data broadcast bus from the host server to the target programmer;

coupling a plurality of electronic devices, each having a non-volatile memory, to a target programmer of a flash memory programming system by a programming bus; and

programming a data image into the non-volatile memory of each of the electronic devices concurrently and asynchronously using the target programmer including;

subscribing to a broadcast message of a programming stream of the data image at a mid-stream logical block address with the programming stream already started,

receiving a logical block of the data image by the broadcast message in a data buffer in the target programmer for programming the non-volatile memory,

copying the logical block concurrently into the non-volatile memory of the plurality of the electronic devices,

verifying the content of the non-volatile memory by comparing the non-volatile memory to the data buffer,

sending an unsubscribe message from the target programmer to the host server after detecting a logical block address wrap with logical address of the logical block repeating the mid-stream logical block address, the unsubscribe message having a list of missing buffers for the data image,

receiving the missing buffers for the target programmer in a sequence based on the unsubscribe message.

7. The method as claimed in claim 6 wherein providing the target programmer includes providing a first target programmer, a second target programmer, a third target programmer, through an Nth target programmer.

8. The method as claimed in claim 6 wherein providing the data buffer in the target programmer for receiving the logical block from the broadcast message including receiving, by a first target programmer, a second target programmer, a third target programmer, through an Nth target programmer, the broadcast message having the logical block.

9. The method as claimed in claim 6 further comprising initializing a logical block address map in the target programmer;

and

wherein;

initializing the logical block address map includes initializing a first target programmer, a second target programmer, a third target programmer, through an Nth target programmer with the logical block address map.

10. The method as claimed in claim 6 wherein receiving the logical block includes receiving a mid-stream logical block, a first of file logical block, and an end of file logical block.

11. A device programming system comprising:

a host server having a data image;

a target programmer of a flash memory programming system, coupled to the host server, the target programmer for subscribing to a broadcast message of a programming stream of the data image at a mid-stream logical block address with the programming stream already started;

a plurality of electronic devices, each having a non-volatile memory, coupled to the target programmer by a programming bus; and

a data buffer in the target programmer configured to receive a logical block of the broadcast message for programming into the non-volatile memory, copy the logical block concurrently into the non-volatile memory of the plurality of the electronic devices, and verify the content of the non-volatile memory by comparing the non-volatile memory to the data buffer; and

wherein;

the target programmer is configured to send an unsubscribe message to the host server after detecting a logical block address wrap with a logical address of the logical block repeating the mid-stream logical block address, the unsubscribe message having a list of missing buffers for the data image, and the target programmer is configured to receive the missing buffers in a sequence based on the unsubscribe message.

12. The system as claimed in claim 11 wherein the target programmer includes a first target programmer and a second target programmer.

13. The system as claimed in claim 11 wherein the data buffer in the target programmer includes a first target programmer and a second target programmer each having the data buffer.

14. The system as claimed in claim 11 further comprising a logical block address map in the data buffer of the target programmer.

15. The system as claimed in claim 11 further comprising a data broadcast bus between the host server and the target programmer.

16. The system as claimed in claim 11 wherein the target programmer includes a first target programmer and a second target programmer coupled to the host server.

17. The system as claimed in claim 16 wherein the target programmer includes a third target programmer through an Nth target programmer.

18. The system as claimed in claim 16 further comprising a data broadcast bus from the host server to the first target programmer and the second target programmer.

19. The system as claimed in claim 16 further comprising a logical block address map in the data buffer of the first target programmer and the second target programmer.

20. The system as claimed in claim 16 wherein the data buffer is configured to receive a mid-stream logical block, a first of file logical block, and an end of file logical block.
