Hi Fabio,
thanks for your details. Some of the discrete switches where messed up. Boot Mode was fine. So now it's working fine.
Even the power button is not needed ;-)
I am glad to know it is working now.
I will create a README file with these jumper settings.
Also, can you please let me know what is your board version? Is it also mx28evk revD?
Yes, revD.
I still have to investigate a little to get USB recovery working. This does not work out of the box as with Freescale'S initial 2009.08 u-boot for this CPU.
Ok, good. m28evk has USB support as far as I know, so maybe you can look at it for reference.
You did not really understand what I mean. I am not talking about using the USBs host/device from u-boot. The i.MX28 is capable to boot via USB. In this case the SOC's ROM implementes a HID device and you can use some tools on your PC (see previous posting) to download the code (boot jumper setting 0-0-0-0. I tried it with Freescale's sb_loader (Wind**s). This works fine when downloading a u-boot (imx28_ivt_uboot.sb) based on Freescale's 2009.08 source + imx-bootlets-src-10.12.01. But it does not work when using sb_loader with u-boot.sb build from the u-boot-imx repo.
I can can imagine that the SPL code somehow breaks the internal download code.
