* | stm32_i2c: handle more unexpected ISR conditions | Andrew Tridgell | 2014-07-12 | 1 | -1/+11 |
| | | | | | | | | this clears the interrupt for more unexpected ISR conditions that otherwise lead to an ISR storm. When that happens no user threads are able to run as the I2C ISR is continually raised Thanks to Lorenz for help in tracking this down | ||||
* | stm32_i2c: check for msgc underflow in I2C ISR | Andrew Tridgell | 2014-07-12 | 1 | -17/+24 |
| | | | | | | a spurious I2C interrupt could cause priv->msgc to underflow, leading to memory being overwritten. This seems to have been the cause of at least some of lockups we have seen | ||||
* | stm32_i2c: ensure we don't change priv-> after semaphore is released | Andrew Tridgell | 2014-07-12 | 1 | -1/+2 |

* | stm32: add sw workaround for broken stm32 hw RTS implementation | Kevin Hester | 2014-05-20 | 3 | -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. | ||||

* | | | stm32_i2c: ensure that unexpected ISR can't overwrite stale data | Andrew Tridgell | 2014-04-28 | 1 | -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 | ||||
