== The RESET line is continuously asserted ==
The last sectors of the eNVM/FLASH are used by the Smartfusion MSS configurator to
store configuration data. In case this memory region gets erased e.g. by
FLASH.ERASE
FLASH.ReProgram /ERASE
or is used by the user code binary the device might not boot properly. In worst
case the RESET line stays asserted continuously. In such a situation please
reprogram the FPGA portion using the Actel/Microsemi FlashPRO tool of by using
JTAG.PROGRAM.JAM <filename>.stp /A "PROGRAM"
. An example for the latter case is available (a2f-eval-kit_program_fpga.cmm).
As the amount of data used for the MSS configuration depends on the user
configuration we do not "guard" any flash-sectors against erasing/writing.
Please refer to the "Smartfusion Microcontroller Subsytem" manual section
"Embedded Nonvolatile Memory – Memory Organization" for more details.
