4.1.5.1 RX Data Block

Structure BSL Core Command

BSL CommandProtectedCMDALAMAHDataBSL Core Response
RX Data BlockYes0x10(AL)(AM)(AH)D1…DnYes

Description

The BSL core writes bytes D1 through Dn starting from the location specified in the address fields. This command differs from RX Data Block Fast in that it returns the status of the write operation.

Note:

When a block is written partly outside the device's memory (for example, starting to write in FRAM but exceeding the end of the memory) the whole data block will not be written.

Protection

This command is password protected and fails if the password has not been sent.

Command

0x10

Command Address

Address where the received data should be written.

Command Data

Command consists of the data D1 through Dn to be written. The command consists of n bytes, where n has maximum 256.

Command Returns

BSL acknowledgment and a BSL core response with the status of the operation. See Section 4.1.4 for more information on BSL core responses.

Example for UART PI

Write data 0x76543210 to address 0x010000:

0x800x080x000x100x000x000x010x100x320x540x760x930xCA

BSL response for a successful data write:
