You can create your own bootloader as a normal SPC5Srudio application, give it the option ''Copy in RAM'' that you can see in the platform component.

This way the bootloader is copied from flash in RAM and then it is executed. Executing from RAM allows you to write another application in flash into an higher address, for example 0x10000, and then jump to it.

Hi  Giovanni Di Sirio

Thanks so much  for your fast response

I see this section it's ok but when my bootloader program get the application from serial port

how can i wrote these bytes to Flash Section ?

I read the documents but i did not find any thing .

I don't know why SPC Studio have not any document for progrmming like other compilers .

Hi,

Flash programming is described in the SPC5xx Reference Manual usually.
