Hello, I have a problem with wiznet w5200. Before the start of implementing the functionality I wanted to test communications by SPI. When I reading values from registers, the data are correct - such as a default data, but unfortunetly when I try to write something, the values in registers do not change - still are the same as default data.
I tried to save the RTR (0x0017), RCR (0x0019), SIPR (0x000F).
Can someone tell me what else i should to do to write data. Maybe is something what i should to do to approve write opperation ?
