r1180 adds a logging capability when log4c is not available.

./configure --with-drivers=pn532_uart --enable-serial-autoprobe
--enable-debug
make clean all

Please provide useful logs to help you.

Hi,

So, could you provide some more logs ?

Could you explain what is a "cakeboard" ? Google show me some strange
stuffs :)
And could you reformulate your last sentence: I did not understand what you
mean.

Can I close this issue ?

How did you do that ? (changing "15 ms time")

Hi,

I am seeing the original problem where no NFC device is found. What was the
solution to resolve that issue?

Thanks

maybe a short sleep in pn532_uart_wakeup() helps?
it works for me...

int res = uart_send(DRIVER_DATA(pnd)->port, pn532_wakeup_preamble,
sizeof(pn532_wakeup_preamble), 0);
CHIP_DATA(pnd)->power_mode = NORMAL; // PN532 should now be awake
+ msleep(1);
return res;

msleep() is some macro defined in pn532_spi.c, or just use usleep(1000)

i an trying to interface Arduino UNO with grove NFC. I added all the
libraries perfectly but the code is written for i2c where grove nfc has
UART connected on the board. it is suggested that de-solder the UART and
solder it to i2c in nfc board, could you please help me in solving the
problem. i need library for interfacing ardunino UNO with grove nfc through
UART.
