GPIO lines on W7500P or WIZ750SR

Question

Hi - if we set the GPIO lines (A,B,C,D) in a certain pattern and then save that pattern, on reboot the pattern has not been saved. we have tried this across the W7500P chip itself as well as the WIZ750SR. we have also tried multiple firmware versions. an example: we set A,B,C,D to 1,1,1,0 however on reboot it returns 0,0,0,0 - see below for actual commands sent. our observation is that it always sets the lines on reboot to whatever GPIOD is. please help! thanks! ========================================================= Commands and abnormal response 1: • Write Cn=1111, Gn=1110, SV, • Read Gn=1110 • Power off, then power on • Read Gn=0000 (Gn should be saved as 1110) Here are the commends 4D 41 00 08 DC FF 00 07 0D 0A 50 57 20 0D 0A 43 41 31 0D 0A 43 42 31 0D 0A 43 43 31 0D 0A 43 44 31 0D 0A 47 41 31 0D 0A 47 42 31 0D 0A 47 43 31 0D 0A 47 44 30 0D 0A 53 56 0D 0A 4D 41 00 08 DC FF 00 07 0D 0A 50 57 20 0D 0A 43 41 0D 0A 43 42 0D 0A 43 43 0D 0A 43 44 0D 0A 47 41 0D 0A 47 42 0D 0A 47 43 0D 0A 47 44 0D 0A (Power off-on) 4D 41 00 08 DC FF 00 07 0D 0A 50 57 20 0D 0A 43 41 0D 0A 43 42 0D 0A 43 43 0D 0A 43 44 0D 0A 47 41 0D 0A 47 42 0D 0A 47 43 0D 0A 47 44 0D 0A =========================================================
