we are observing weird error during initilization...enclosed the log dump (board2_init_fail_log.txt and ll13_01_board2_success_logs.txt)on Raspberry pi with 2 NFC03A1 boards (SPI3.0 works well, SPI0.0 fails)2 independent binaries are being used with ...

re run with gpio set/clear prints. .. same results. enclosed the logschecked the connection and also gpio pu state. seems to be correct...i manully pulled up the pin state...somehow i have a doubt about the timing response of the chip.. some times on...

1. Yes, separate sets of pins are allocated for SPI Chip Select, IRQ_IN and IRQ_OUT for each board.2. Yes i have removed the gpio set /clear prints. i will include the same and re run3. will check IRQ_OUT pin, can you clarify what you mean by wrongly...

when we build will this not throw link errors ? can you clarify command line parameter differentiating the instances ?question was how will 2 readers detect the tags, what if both the readers detect, how do we differentiate..we would like to create a...

Sorry for the delayed response Brian... i was OOO.we will be using T2T and T5T (14443A and 15693 tags).for now we will go with NDEF formatted messages.. i am not sure of raw proprietary datado you see any advantages between them ?

so 5V is not used, only 3.3v is used right.. i did have a look at the schematics and didnot see any +5v connections.we were able to detect the tag after connecting 2 seperate 3.3v, CN6.2 and CN6.4 .. i think we missed CN6.2, may be thats the reason w...
