2011-11-03Use NFC HAL for some libnfc settings.android-sdk-4.0.3_r1android-sdk-4.0.3-tools_r1android-cts-verifier-4.0_r1android-cts-verifier-4.0.3_r1android-cts-4.0.3_r2android-cts-4.0.3_r1ics-mr1Martijn Coenen
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
2011-10-25Use a 10s timeout in uart_read() in FW download mode.Nick Pelly
This provides a path to flush RX, necessary when we enter FW download mode with bogus data already in RX. This fixes a problem where NFC was dead on several HSPA and LTE devices. Also decrease FW timeout completition from 120s to 60s. Typically FW download takes 30s, and 120 is unnecessarily large and causes a long delay to bring up NFC when we need to retry FW.

2011-10-21Fixes to LLC and DAL to handle unreliable UART.Nick Pelly
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.

2011-09-09Patch to add an API to load a FW image in the libnfcDaniel TOMAS
This new API permit to load the PN544 FW image when a download is needed at boot time. Change-Id: I2b3406d7ae0f0211123bd680ef914e9948c81eef
2011-07-14Disable read() timeout.Nick Pelly
During normal operation, there is a pending read of 1 byte. This reverts an earlier change to make FW download more stable. Will need to revisit this again, but fow now we have other FW download fixes in place that make FW download ok. So now its better to optimize normal operation. With this change NFC becomes reliable again on Prime. Change-Id: Ie5ea1c58ae7ddeb0359f344b9ceb6478b00f2158
2011-07-08Return partial response on timeout during uart read()Nick Pelly
This is just to match the behavior in the old uart read DAL. It does not actually fix any problems, just pushes errors higher in stack. Change-Id: Iee065f39a006804be2618c3704e32b3f41a8a59e
2011-07-012 second timeout on read().Nick Pelly
This restores the previous DAL behavior for read. It turns out this is a necessary hack to allow us to abort a pending read when switching to FW download mode due to a non-responsive NFC controller. Change-Id: Ief6f82600bb0603daaa50097a54a5ac42ae0f6b4

2011-06-22Implement power control and firmware download for UART.Nick Pelly
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
