R
Start Address: Address from where data bytes are to be read. This address
should be a word boundary.
Number of Bytes: Number of bytes to be read. Count should be a multiple of 4.
CMD_SUCCESS followed by <actual data (UU-encoded)> |
ADDR_ERROR (Address not on word boundary) |
ADDR_NOT_MAPPED |
COUNT_ERROR (Byte count is not a multiple of 4) |
PARAM_ERROR |
CODE_READ_PROTECTION_ENABLED
This command is used to read data from RAM or Flash memory. This command is
blocked when code read protection is enabled.
"R 1073741824 4<CR><LF>" reads 4 bytes of data from address 0x4000 0000.
P
Start Sector Number
End Sector Number: Should be greater than or equal to start sector number.

INVALID_SECTOR |
PARAM_ERROR
This command must be executed before executing "Copy RAM to Flash" or
"Erase Sector(s)" command. Successful execution of the "Copy RAM to Flash" or
"Erase Sector(s)" command causes relevant sectors to be protected again. The
boot block can not be prepared by this command. To prepare a single sector use
the same "Start" and "End" sector numbers.
"P 0 0<CR><LF>" prepares the Flash sector 0.
