Hello, From the contents of CONTROL.CONTROL_STATUS[5:0] on my IGEP0030 module it looks like the sys_boot[5:0] bits are 0b110000, which is a boot order of: USB UART3 MMC1 OneNAND Is there any way to pull down the sys_boot[5] pin to turn off peripheral booting so that the boot order is: OneNAND USB UART3 MMC1 The problem with the first boot order is that booting from OneNAND takes several seconds just to get to the x-loader. Many thanks, Holger

    It\\\'s possible changing some resistors in hardware. ISEE provides this service for high volumes.

    Unfortunately I am not a high volume customer, but my company has the facilities to work with small surface mount components. I assume that the sys_boot configuration is done similar to the beagleboard, with pairs of 10K resistors connecting sys_boot pins to either 1V8 or GND? If this is the case then all I am after is the resistor pair that is connecting sys_boot[5] to GND and 1V8. I think it has been mentioned before in this forum, but if the schematics for the IGEP0030 module were available then a lot of these kind of questions would not need to be asked. Many thanks, Holger

    Well I can\\\'t decide this. Have you tried to contact ISEE and ask for them ?
