Hi kmshim

It's really work :) thanks, thanks, thanks :).

.

.

.

but why !!! after system reset

FMI_CR : set to reset value

FMI_BSSR :not changed

FMI_BBADR :not changed

FMI_NBBSR :not changed

FMI_NBBADR :not changed

In my opinion, this is a BUG.

Hi, gajer

In the case of H/W remap by FLINK or RLINK,

BANK0(at 0x80000), BANK1(at 0x00)

when globla reset is occued,

SCU_PLLCONF :reset value

SCU_CLKCNTR :reset value

SCU_SYSSTATUS:reset value

FMI_BSSR :reset value

FMI_BBADR :reset value

FMI_NBBSR :reset value

FMI_NBBADR :reset value

FMI_CR :reset value(0x08--->only bank0(Boot setcor) enabled)

when system reset is ouccued,

SCU_PLLCONF :not changed

SCU_CLKCNTR :not changed

SCU_SYSSTATUS:not changed

FMI_BSSR :not changed

FMI_BBADR :not changed

FMI_NBBSR :not changed

FMI_NBBADR :not changed

FMI_CR :0x08(reset value(0x08 --> only bank0(boot sector)enable)

I think that your problem because of FMI_CR, that is bank1 is disabled by reset value of FMI_CR.

I propose that you modified start code to what i recommaned previously and application jump(0x00 --> 0x80000), and don't use the software remap..

good luck,,

Best regards
