Hi,

I need some example of imx-bootlet file to boot the imx233 using only the internal linear power supply. Is this code available? Could I send my code that needs to checked?

Thank you in advance for your support.

HI Francesco

one can check 5V only mode, it is well tested on i.MX28 EVK

Updates and Patches (9)

Linux patch for i.MX28 SDK 2010.12 to add the most robust support

possible for a VDD5V or DCDC_BATT only configuration.

i.MX28 Evaluation Kit|Freescale

processor works from LDOs until hw_power_Enable4p2DcdcInput()

in hw_power.c imx-bootlets.

Best regards

igor
