C6727 ROM Functions, are they "callable" ? ie the boot loader?

Rick Bogdan

Given the Boot loader is actually in ROM but not advised to use with the I2C or SPI port ..  could our secondary boot code set-up the I2C or SPI port and then call the boot loader function in ROM ? In other words is the ROM Boot loader function “callable” ? ...  Is it possible to call the AIS functions in ROM just like we can call DSP functions in ROM?

    Rick,

    C6727 bootloader supports AIS version 1.0 and does not support the Opcode corresponding to Function execute so ROM functions on C672x are not callable. Please refer to section 3 in the bootloader app note to see supported opcodes. This functionality is supported on C674x family bootloaders but only to change PLL, Power, pinmux, clock and EMIF configurations.
