I am using w6100 on TI DSP 28377D. I am contacting you because I want to minimize modification of Iolibrary due to MISRA 2012 C reliability test. I have organized the parts that must be modified so far, but I am contacting you if Wiznet can help me with minimal modification. 1.socket.c 85 lines - When using C89 ANCI, for(uint8_t i =0;i2. wizchip_conf.h 151 lines - When assigning EMIF memory address used by TI to _WIZCHIP_IO_BASE_, W6100 register R/W error occurs Guessing - Assign EMIF bus address ex) 0x00100000 to IDM_AR0, IDM_AR1, IDM_BSR, IDM_DR macros => Add #define _WIZCHIP_IO_BASE__ 0x00100000 #define _WIZCHIP_IO_BASE_ 0x00000000 #define _WIZCHIP_IO_BASE__ 0x00100000 - You need to add define as above to R/W W6100 register normally - Guessing, Like the WIZCHIP.IF.BUS.write_data(IDM_AR0, tAD,3,1) function, IDM_AR0 represents an external bus address, and tAD represents a W6100 address. It seems that the register can be used normally by adding the address in the function. => So the conclusion is that the IO_BASE input variable is needed for EMIF or other external interface expandability in the W6100 Iolibrary. 3.w6100.h, after line 247 - If you write 0x2000 << 8, the actual intention is 0x00200000, but it may be read as 0x0000 depending on the system. Please consider changing it to 0x00002000 for system expandability.
