| * nfc-hal: generalize error handling in Reader thread.Rakesh Goyal2012-03-091-5/+16
| | | | | | | | | | | | | | | | | | If host runs faster than the nfc chip, it tries to read response immediately. In this scenario nfc chip responds back with it's read address and software should ignore this data and retry. This patch generalizes the retry mechanism to accomodate other versions of the nfc chip.

* Use NFC HAL for some libnfc settings.Martijn Coenen2011-11-031-18/+46
| | | | | | | | | | The NFC HAL in libhardware allows us to store and retrieve product-specific settings. This patch moves two product-specific settings to the HAL: the device port, and the usage of the i2c workaround we had for crespo. This means configuring the port no longer needs to be done from JNI land. Change-Id: I2e19b6f188f808bc2f2a1f1abc28f2a6c47e6a4c
* Fixes to LLC and DAL to handle unreliable UART.Nick Pelly2011-10-211-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a 100ms timeout in uart_read() when reading LLC payload only. Allow 200 retries on host. Note that we use pn544 timeout retransmit instead of an explicit REJ (do not use CRC_ERROR_REJ). The reason is that after a dropped frame, a host timeout on read() is the only reliable way to recover frame alignment, but if we send an immediate REJ then we are constantly reading and can never regain frame alignment. Also note that the pn544 timeout (200ms) is higher than the host (100ms). This allows the host to abort a partial read and return to known state before the pn544 re-transmits. We have to turn off timeout for FW mode. Typical read time is ~100ms, but some are 1 second+ Modify DAL & LLC layer to more reliably handle partial frames by searching for a LLC length byte again, and log the various error paths. Also introduce debugging tools: debug.nfc.LOW_LEVEL_TRACES 2 Will enable LLC header decoding in the trace output. Only read at NFC init time, use /data/local.prop to enable. debug.nfc.UART_ERROR_RATE X Will randomly inject errors at the uart transport, with a probability of X/1000 for every byte. 50% of those errors will be a dropped byte, 50% will be corrupted. Recommend X=10. FW mode can't handle any errors. Can be enabled after boot. adb shell dumpsys nfc Will now print the number of errors detected at the LLC layer.

| | | | | | | | | | | | | | | | | | | | | | | | | | Also clean up some UART and I2C DAL functions. o Re-enable FW download o Use /system/vendor/firmware for pn544 firmware now o Clean up read() and write() paths for both I2C and UART o Use new sysfs entry for power and FW control on I2C platforms o Remove userspace sleep()'s on power control toggle. They are now done in the kernel as they should be. Change-Id: I39956d36e02c1eb526a5c546bd3cb74edce4ff18
