The pinmux settings are taken care of by the ROM boot code when it is determined that a UART boot should take place, whether that is due to initial switch settings or due to a fall back from another failed boot mode (NAND or UHPI).

It happens on the DVEVM, we checked. But then, the UART0 pins are MUXED with GPIO35 and 36. On power-up, it is set to GPIO. It can be set by software to UART. So who sets it to UART mode on DVEVM? regards, -Ketan ________________________________ Check out what you're missing if you're not on Yahoo!
