Which flash driver are you using? Can you erase / program the flash using a JTAG debugger?
I am using a precompiled u-boot image from the board's vendor (Toradex AG.).
Then you should probably ask the vendor's support folks.
Where can I check the type of the selected flash driver?
In the source code. You received the source code or at least a written offer for it with your board, didn't you?
I have downloaded the u-boot image to the board via jtag (jflash utility), so it is working.
OK.
I have some interesting thing in the u-boot output: Bank # 1: INTEL 28F128J3A Size: 32 MB in 128 Sectors
On the board I have two flash chips (2x16MB) of the type 28F128J3C150. Is it OK? I think I had to see two bank of 16MB each.
I guess it's OK. I don't know your hardware, but most probably both chips are operated as 2 x 16 bit in parallel to form a single 32 bit wide bank.
Unfortunately they never bothered to submit their code back to the public source tree. All I know is that Detlef Vollmann once (August 2005) mentioned that there is some port, but he never submitted a patch either.
