Andy Piper 4c2cbdab8d AP_HAL_ChibiOS: only setup half-duplex for receive when transmit is fully over 2021-02-17 20:09:48 +11:00
Andrew Tridgell 9de1519928 HAL_ChibiOS: prevent hw flow control from hogging a DMA channel 
When hw flow control is enabled check the CTS pin before we grab the
DMA channel to prevent a long timeout trying to send to a blocked port
from holding a DMA channel against another device

this fixes issue #16587
 2021-02-15 07:23:56 +11:00
Andrew Tridgell 4d171ec19a AP_HAL_ChibiOS: support uartI, allowing a total of 9 uarts 
this allows for OTG2 on the MatekH743 board, which makes SLCAN much
easier
 2020-11-30 14:09:31 +11:00
Andrew Tridgell 46976c4358 HAL_ChibiOS: fixed remapping of ioline_t with BRD_ALT_CONFIG 
when a peripheral is made available via BRD_ALT_CONFIG we need to
remap the existing ioline_t in the UART and I2C drivers to use the new
pin.

This fixes an issue with half-duplex, inverted, swapped UART pins for
protocols like FPort and FPort2

Andrew Tridgell 989f8c5d41 HAL_ChibiOS: fixed a race condition in UART DMA transmit 
this fixes an issue seen on one board which caused a watchdog on high
uart DMA load. We have reproduced the issue on another board by
forcing a very high DMA transfer rate on the same DMA channel while
also requesting very high transfer rates on the UART. The likely race
is in the DMA transmit timeout code, and the simplest fix is to lock
out interrupts during the DMA setup to ensure the tx timeout cannot
trigger during the setup

Andrew Tridgell e8ab35a192 HAL_ChibiOS: fixed stdout in early startup bug 
this caused a failure to boot on some boards if they tried to print
messages in early startup code before hal was initialised

thanks to @Shadowru for reporting the issue
 2020-02-12 13:51:10 +11:00
Andrew Tridgell 982cff0695 AP_HAL_ChibiOS: make all semaphores recursive

can occur on less used code paths

Andrew Tridgell 4b4642dd4d HAL_ChibiOS: allow handling of much higher receiver baudrates with DMA
