If yes, why don't you use that? It's almost same, but one firmware was loaded in I2C mode as one I2C device was probed, and operate slavers by address. And with SPI mode, we probe two SPI devices in current case, so will load two firmware binary, and some operation need to be processed as special case, for example, under SPI, read need one byte shifted if page number is large than 1. > > Thanks, > Gergo > >
