How about my 3 patches? I'm looking forward to your reply. Thanks.
They are sitting in my queue waiting to be reviewed and eventually applied or rejected. Please be patient.
Here is a manual webpage for SBC-2410X (in Chinese): http://www.arm9.net/matrix-v.asp
Is there an English manual, too?
Recently, I am working on making U-Boot boot from nand on SBC-2410X board. Do you think it is meaningful? In my opinion, nand flash has at least advantages
This can be an issue if you have really high volumes of your boards and try to minimize the production cost at the expense of reliability.
¡®Steppingstone¡¯. When booting, the first 4 KBytes of the NAND flash memory will be loaded into Steppingstone and the boot code loaded into Steppingstone will be executed."
Here you see the problem: you will need a separate first stage loader to do all the low level initializations and then load U-Boot to RAM like it has been implemented on some other systems before. The probelm is that all comfort you have witrh U-Boot during board bringup and U-Bootporting gets lost this way.
Correspondingly, YAFFS, a NAND-flash friendly filing system, will be a good choice to be added into U-Boot.
Feel free to submit patches.
