Dear all ,

 

I am working with bf 548 in one of our custom board , trying to use nfc driver in Lwip ethernet application , it fails

1 - If i do nand reset and then do rd/wr to nandflash it fails , and then after my lwip application also fails .

2 - if i use NFC driver in standard application it works perfectly , without any problem .

 

i tried to debug what can be the problem is but iam not able to figure out  , my sequence of using nfc driver with lwip is

 

nand reset ( ok ) --> nand initialization (ok)  --> rd/wr ( fails) -> lwip ip configuration (link establishment - ok )-> lwip tcp socket creation( fails ) .

 

i have attached the worknig NFC driver in standard application ( from analog devices) ,

Please help , completely hanged up , not able to proceed .

 

Thanks and regards
