am335x custom board without SD-card but usb

Hi,

Thanks for theses links. I pass through the first document( about u-boot), it talks about boot_modes/USB but this is not explained at the following ... Is it possible to start u-boot on an key at the first boot of a production board or should I use JTAG ?

Thanks a lot

Mickael

Hi Mickael,

From what I read you are trying to boot from USB in Host mode. This is not possible. Please read section 26.1.8.6 from the AM335X TRM Rev. K. For production the Uniflash tool can be used: http://processors.wiki.ti.com/index.php/Sitara_Uniflash_Quick_Start_Guide

Hi,

I am trying now to use Uniflash on Linux. I have a problem when I try to execute it, I have a message : Please SET DISPLAY . CSS Uniflash v3 cannot be installed to console mode. Do you have an idea ?

Thanks in advance

Uniflash is supported on the CCS forum: http://e2e.ti.com/support/development_tools/code_composer_studio/f/81 Please ask there.

My u-boot-spl boot now, (I used a bad image). I have to configure network it says No ethernet found. No ethernet devices found.

I change my botoargs to :

console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/ram0 rw initramfs=0x81000000,8M init=/init ip=off omap_vou ....
as mentionned in documentation.

That's boot, but the surface flinger failed to load, and the platform crash ...

H,

I am still on my problem of boot, Android doesn't see the good size of the data partition (10 Mbytes instead of 512M) whereas it is able to mount other partitions of 512 Mb. Do you have an idea ?

Thanks in advance
