4.3.5 Program Data Fast

Structure

Header Length CMD Address Data CRC32
0x80 L1 L2 0x24 A1...A4 D1...Dn C1 C2 C3 C4

Description

The Program Data Fast command is identical to the Program Data command , except that this command performs the non-blocking write, to speed up the programming process. To this command BSL will not send the BSL core message response to indicate if the programming was successful.

Protected

Yes

Address

Start address of the memory region to be programmed. A1...A4, where A1 is the least significant byte of the 32 bit address.

Data

Data bytes to be written in the specified address. Maximum size of the data that can be sent is limited by the Buffer size of the device. Buffer size is known from Get Device Info command .

Command Returns

BSL Acknowledgment.
