== 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. |
