hello,

a custom board of mine is equipped with a 16-bit flash from fujitsu (amd compatible). the flash is used in 8-bit mode. unfortunately it seems that the cfi component does not support 16-bit flashs that are used in 8-bit mode. is there any information about this problem? the curious thing is hat the flash programmer of the ide is working well but the cfi component not

bye,

niosIIuser,

You're quite correct there was a problem in the CFI flash component, which has been fixed in the 1.01 release.

The reason for a difference in behaviour between the component and the flash programmer, is that the flash programmer does not use the component. In the case of the flash programmer the code to read the CFI table is in the host based executable. The CFI flash component is used if you wish to program flashes from you code running on Nios

Hope that helps
