Hello!

I'm having some problems to switch from secondary to primary flash !

My Memory Map (start):

rs0: 2000~3fff

csiop: 200~2ff

FS0: 0000~7FFF PAGE0 code space

FS1: 0000~7FFF PAGE 1 code space

FS2: 0000~7FFF PAGE 2 code space

CSBOOT0: 0000~1FFF data space

CSBOOT1: 2000~3FFF data space

CSBOOT2: 4000~5FFF data space

CSBOOT3: 6000~7FFF data space

When I execute the command:

PSD8xx_reg.VM = 0X12;

I jump from the primary Flash to the secondary, where i have the same firmware, but I canâ€™t come back using the command:

PSD8xx_reg.VM = 0X0C;

Please, what I'm doing wrong? Somebody can help me, please?

No, I'm not sure.

I know that my program doesn't work when I try to come back to the primary flash, and when I jump from de primary flash to the secondary its works just if both programs are very similar.

I donâ€™t find anything in the datasheet, I thing that when I change from one block to another the program counter donâ€™t change to the beginning of the program. Is it correct? How can I do this?

Can you help me, please ?

Thanks
