RM57L843: Migrating from TMS570LC4357 to RM48L843

Hi Spandana,

The easy way is to generate RM48L843 HW driver using HALCOGen, and port your application code to the new project.

RM48 is a little endian device, but TMS570LC43x is a big endian device. If you access the registers or memory content in byte mode, you need to swap the byte orders. For example, 

1. TMS570

#define SPI1_TX_ADDR ((uint32_t)(&(spiREG1->DAT1)) + 2)
#define SPI1_RX_ADDR ((uint32_t)(&(spiREG1->BUF)) + 2)

2. RM48

#define SPI1_TX_ADDR ((uint32_t)(&(spiREG1->DAT1)) + 0)
#define SPI1_RX_ADDR ((uint32_t)(&(spiREG1->BUF)) + 0)

Hi Wang,

Thanks for your feedback. We'll proceed with the help of HALCOGen and take care of the endianness.

I would like to have your reference for boot loader for both the controllers.

Can you please here?

Thanks
