Jumping (currently rebooting, see crosbug.com/p/8100) to the RW image should be done by vboot_init(), not vboot_pre_init(). As currently written, vboot_init() has to come AFTER these function calls: task_init(); // sets up interrupts so that uart will work watchdog_init(1100); // in case we fall over somewhere uart_init(); // we'd REALLY like to see some debugging output system_init(); // may go away with crosbug.com/p/8100 keyboard_scan_init(); // check for F3 to go to recovery mode flash_init(); // maybe set RO regions (this should come earlier!) eeprom_init(); // this is where the try_b flags are kept BUG=chrome-os-partner:7459 TEST=none Signed-off-by: Bill Richardson <wfrichar@chromium.org> Change-Id: I0ec3f6bcc26a308bb1005a944990963853b88b60
