Hi,
First post here, so apologies up front...
I was wondering what the status of support for DA8xx in u-boot is.
Is
anyone working on that?
There is unfortunately 0 support.
The reason I ask is that I have made an initial port for the TI
da830
evm board which seems to be working (serial, ethernet dhcp & tftp
and
i2c tested) and seems capable of booting Linux at least.
That's what U-boot is about :-)
It is based on GPL code from several sources, not least of which is
from
TI's old 1.3.3 version of u-boot, but I have updated it to support CONFIG_NET_MULTI and sorted out the padding changes in the ns16550 driver CONFIGs. It uses already present davinci drivers where
possible.
I have interest in getting at least USB and NAND support working as
well
- maybe SPI FLASH too - and will work on that as access to hardware
allows.
All these are present in the 1.3.3 version so all you have to di is up port
My git tree is up to date, but I'm new to git too, so I have no idea
how
to dump a patch.
There is a GIT manual. But just google'ing will also help
Regardless, I wanted to check I'm not treading on anyone's toes
first
and to gauge interest, especially as TI appear to have done some
work on
this in the past.
Ti will add support but I don't know when. If you so wish you can post your own version.
If you decide to submit patches please submit against u-boot-ti
Bye, Nick.
Thanks, Sandeep
My main motivation for this port is to escape the NAND support in 1.3.3 :-) It stores compressed ECC in a non-standard way, puts data in the OOB area on 2K page devices and only supports ECC1. I'm concerned that all these things will come back to bite me later.
Thanks for the pointer to the u-boot-ti tree. I will rebase my changes against that and try to split my diff up into patches smaller than the current 137kB. Should I use this mailing list, or another one, for RFC submission?
Thanks, Nick.
