Yes
Data
16 byte factory reset password stored in the BCR configuration memory. The default password is all 0xFF.
Password is required only when Factory reset is "Enabled with Password" in BCR configuration.
Command Returns
BSL Acknowledgment and BSL core response with Message about the Status of the operation. See
4.4.1
for more details.
After doing the factory reset, until the Non-main configuration has been restored, the system is
highly vulnerable to a potential lockout situation in which it is impossible to get access to the device
again.
Example
Host: 80 01 00 30 DE 20 24 0B

Description
This command is used to verify the CRC of the data stored at the given memory range. This enables faster
verification of the programmed data. It requires the data size to be minimum 1kB.
CRC verification is allowed for Main flash (application memory), Non-main Flash (configuration memory) and
SRAM memory.
SRAM memory is not fully accessible by the Host. Refer
Protected
Yes
Address
Start address of the memory region to be verified. A1...A4, where A1 is the least significant byte of the 32 bit
address.
Data
Size of the data to be verified in bytes, L1...L4, where L1 is the least significant byte. 1kB <= size <= 64 KB.
Command Returns
BSL Acknowledgment and BSL core response with CRC value calculated for the requested memory region.
Refer
Section
4.4.5for more details.
If the verification command, had invalid address / length, the corresponding error will be sent as the Message
Response following the BSL acknowledgment. Refer
