Change some register values of SYSCFG0 with secure boot INI file

Hi All,

There is a question on INI file which I hope it does not take much your time. When trying to modify some values of system configuration module0(SYSCFG0), inside DSP C6748, such as HOST1CFG, IRAWSTAT, FLTADDRR, FLTSTAT from INI file by adding the following lines, it is not effective. In addition, whether bootExitType is set as SECUREWITHSK or NONSECURE does not make any changes.

;HOST1CFG
[AIS_Set]
TYPE=2
ADDRESS=0x01C14044
DATA=0x700001
SLEEP=0

;IRAWSTAT
[AIS_Set]
TYPE=2
ADDRESS=0x01C140E0
DATA=0x0
SLEEP=0

;FLTADDRR
[AIS_Set]
TYPE=2
ADDRESS=0x01C140F4
DATA=0x0
SLEEP=0

;FLTSTAT
[AIS_Set]
TYPE=2
ADDRESS=0x01C140F8
DATA=0x0
SLEEP=0

Could you show me some clue to change these registers?

Thank you in advance,

An.

    Hi Mr An,

    You cannot configure all system registers through the ROM boot loader. Only PinMux, PLL, PSC, SDRAM setting, MPU and IOPU, CRC check setting can be set by the boot loader. Also I am not sure why you are trying to modify the HOST1CFG register to provide the entry point. The AIS image finds the entrypoint from the application image so this will get configured when you provide out file to the Secure_HexAISgen tool to where ever the _cint00 is defined in the map file of the binary.
