Hi Fabio,
can you confirm that the current u-boot-imx tree runs fine on the MX28EVK? I tried it but the debug console stays dead.
Yes, it works fine.
This is what I did:
- make mx28evk
I think you meant "mx28evk_config"
- make u-boot.sb
- ./tools/mxsboot sd u-boot.sb u-boot-sd.sb
- prepare an SD card as described in doc/README.m28 (only one partition
of type 53) 5) dd u-boot-sd.sb to above partition 6) install SD and press power button
On my board I don't have to press the power button in order to get the console output.
Please check your MX28EVK settings:
- Boot Mode Select: 1 0 0 1
- JTAG PSWITCH RESET: To the left (reset enabled)
- Battery Source: Down
- Wall 5V: Up
- VDD 5V: To the left (off)
- Hold Button: Down (off)
Also, I have only tested this on a MX28EVK rev.D board.
BTW: Did you ever try Freescales sd_loader to download u-boot into RAM?
FYI: There also seems to be a Linux version of the USB loader (http://svn.rockbox.org/viewvc.cgi/trunk/utils/imxtools/).
I haven't tried this yet.
