Hii all,
We have a project on dm355. Our software is nearly completed and we
begin to test our mainboard with our software after the test on
dm355-dvevm. But we have a problem. We could not find the nand flashes
on dvevm RevC to buy (they are MT29F16G08FAA) and bought MT29F16G08QAA
chips to use with dm355. The difference is only the block size of nand
chips. FAA is 128kb block size and QAA is 256kb block size. We are using
Ronetix Peedi as debugger and flash programmer.
The davinci.wiki says that dvevm and uboot are compatible with both nand
chips but i dont think so. because if we program flashes with ubl,uboot
and kernel on MT29F16G08FAA (the orginal flash dvevm revc has) our board
is booting and everthing is ok but if do this procedure on MT29F16G08QAA
it is not boothing. After that ronetix technical support has changed
the ubl codes to make that ubl finds uboot and then ubl and uboot has
worked. But the biggest problem is now...
uboot that comes with dvevm and (latest update too) can not write on
MT29F16G08QAA. if i change the uboot environment variables and save
environment it is gives output like everything is fine and the writing
is successfull but after reset i see that the changes that i do on
environment variables are gone. it has the default environment variables
and configuration.
when i try to load and write the kernel on the MT29F16G08QAA again it
gives output like everything is fine and writing is succcesfull. But
when i try to boot kernel from that directory it gives me ECC error .
The console outputs of my minicom session is attached to my mail.
Please if anyone has ideo on this problem, give me help or direction to
overcome on this problem.
Thenk you for read and help.
