Hello,
I'm working with Rz/A1L family controller and is interesting to program the flash with my SW and run it from RAM on power on.
When I'm working with evaluation board((R7S721021 controller), I'm successfully programming the flash from the e2studio and it works
When I'm doing the same with the custom board((R7S721020 controller), it seems like it is programming to the flash exactly as with evaluation board, but the code not running
According to datasheet: "In boot mode 1, booting up is from the serial flash memory connected to the SPI multi I/O bus space. In this mode, this LSI operates as follows: After the power-on reset is canceled, the boot program stored in the on-chip ROM (starting from H'FFFF_0000) is executed."
My question is does this boot program is programmed in every controller by the manufacture? May be my problem is that this boot program is not stored? How can I check it? Can I program it from e2studio? Can I verify that the flash was programmed correctly?
Best Regards,
Alex
