* stm32: add sw workaround for broken stm32 hw RTS implementationKevin Hester2014-05-203-7/+134
| | | | | | | | | | | | | | adds support for manually asserting nRTS when the OS buffer is nearly full and deasserting it when it has room again. This makes the RTS pin actually work in a useful way (the stm32 hw implementation is broken - it asserts nRTS as soon as more than one character is received). We assert nRTS from inside of up_recvchars. For deassertion we needed a new callback from the general serial device layer when characters have been dequed. onrxdeque was added to uart_ops_s for this purpose and implemented (currently) only on the stm32.

| | | | | | This reverts commit 099b2017ccfa0fc7696f168db2a0c2e13fe5edbc. This is only a temporary measure to gain the time to apply a more complete fix without side effects.

* | | stm32_i2c: ensure that unexpected ISR can't overwrite stale dataAndrew Tridgell2014-04-281-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | if we get an ISR leftover from a previous read transfer it could use stale values for priv->dcnt and priv->ptr to overwrite stack that is no longer in scope. This resets dcnt and ptr on each new stm32_i2c_process() call to ensure that any unexpected data bytes are discarded

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | waiting for write completion and checking the status register on read will improve the chance that we catch IO errors immediately rather than on the next IO. This improves the chance that callers will be able to take reasonable action on IO errors. We have one example board that does give intermittent IO errors, and this change helps for that board
