With the V2 core Infineon has introduced the PSRAM on the XC16x derivatives. Does anybody have any good pointers to further documentation on how best to use this memory for in system flash reprogramming ? What I am naively envisaging is having a C-callable function as part of my standard code (stored and executed from on-chip FLASH) which when called would copy some form of bootloader code into the PSRAM, transfer control to there, then load the new target binary say from external RAM (or serial port), reprogram the flash and then restart execution from flash !? I guess this is feasible or am I missing something vital ? Any tips, examples or hints gratefully received. Thanks, J. PS: Keil v5.0 / XC161CJ
