Hi,
the board uses an Freescale i.MX35 Controller.
When I use the u-boot revision 2013.01.01 with same configuration all works fine (-1 disables autoboot) Only when I use u-boot 2013.07 it does not work. I have looked in main.c and found the following differences:
2013.01.01: Line 68: #if defined(CONFIG_BOOTDELAY) && (CONFIG_BOOTDELAY >= 0) 2013.07: Line 88: #if defined(CONFIG_BOOTDELAY)
2013.01.01: Line 298: #if defined(CONFIG_BOOTDELAY) && (CONFIG_BOOTDELAY >= 0) && defined(CONFIG_OF_CONTROL) 2013.07: Line 286: #if defined(CONFIG_BOOTDELAY) && defined(CONFIG_OF_CONTROL)
Could it be, that -1 Value for disable autoboot is not longer supported in u-boot 2013.07?
Regards Mario

Hi,
i am using u-boot 213.07 and hav set CONFIG_BOOTDELAY to -1 to prevent autoboot. But u-boot seems to ignore the parameter and do autoboot after 1 second. Could someon please help why I cannot disable autoboot?
Do you by chance have 'bootdelay' saved in a persistent environment?
If memory serves, the 'bootdelay' environment variable over-rides the default from the CONFIG variable.
what board is this on?
