Leonard Hall 05a896cc4c AP_HAL_ChibiOS: don't fake CAN send success in bootloader builds 2026-08-04 12:04:45 +10:00
Thomas Watson f4ae5d7901 AP_HAL_ChibiOS: drop CAN log message calls 
The infrastructure for these has been continually buggy and rarely used.

Delete calls in preparation for ripping it out entirely.
 2026-05-18 20:58:47 -05:00
Thomas Watson 048f4d9b60 AP_HAL_ChibiOS: drop CAN interface alternate mode support 
Only "NormalMode" was ever used; the others had rotted or were never
implemented.

Thomas Watson 763a6361de AP_HAL_ChibiOS: drop CAN filter support from HAL 
Has been unused since the removal of libuavcan.

Thomas Watson 0e4db74c75 AP_HAL_ChibiOS: ignore rare CAN modes 
These are never used anywhere by ArduPilot.

muramura 4a9ddef8ee AP_HAL_ChibiOS: Change division to multiplication 2025-01-02 23:22:42 +11:00
Peter Barker 8b9154d115 AP_HAL_ChibiOS: re-order initialiser lines so -Werror=reorder will work 2024-09-24 22:50:28 +10:00
Andrew Tridgell 05d43fd00b HAL_ChibiOS: allow for MCAST UDP with no CAN link 
this allows the CAN interface to operate without a CAN cable, allowing
for bridging of MCAST UDP CAN

Andrew Tridgell e8b4010899 HAL_ChibiOS: fixed CANFD timings (again!) 
the timing table was not correct, thanks to APD for pointing this out.

This is recalculated from
https://www.kvaser.com/support/calculators/can-fd-bit-timing-calculator,
with transmitter timing delay compensation added and tested with Salae
captures to ensure we are getting the right bit rates

Andrew Tridgell a2707b48c5 HAL_ChibiOS: enable clock management on G4 
this allows for a different clock tree in the main fw from the
bootloader

Andrew Tridgell 2d031a4d20 HAL_ChibiOS: switched G4 FDCAN clock to 80MHz 
this requires main CPU clock at 160 MHz instead of 168 MHz

Andrew Tridgell 1c8048df8f HAL_ChibiOS: fixed CANFD timings 
our CANFD timings were resulting in a lot of busoff errors. Here is an
example of master at 1Mbit/5MBit:

Getting @SYS/can0_stats.txt as -
------- Clock Config -------
CAN_CLK_FREQ:   80MHz
Std Timings: bitrate=1000000 presc=7
sjw=0 bs1=7 bs2=0 sample_point=90.00000%
FD Timings:  bitrate=5000000 presc=1
sjw=0 bs1=5 bs2=0 sample_point=90.00000%
------- CAN Interface Stats -------
tx_requests:    2689
tx_rejected:    0
tx_overflow:    443
tx_success:     7
tx_timedout:    2232
tx_abort:       0
rx_received:    18470
rx_overflow:    0
rx_errors:      0
num_busoff_err: 34439
num_events:     18477

fdf_rx:         18467
fdf_tx_req:     2182
fdf_tx:         0

here is an example with the new timings:

------- Clock Config -------
CAN_CLK_FREQ:   80MHz
Std Timings: bitrate=1000000 presc=8
sjw=1 bs1=8 bs2=1 sample_point=90.00000%
FD Timings:  bitrate=8000000 presc=2
sjw=3 bs1=8 bs2=3 sample_point=80.00000%
------- CAN Interface Stats -------
tx_requests:    3023
tx_rejected:    0
tx_overflow:    0
tx_success:     3023
tx_timedout:    0
tx_abort:       0
rx_received:    27865
rx_overflow:    0
rx_errors:      0
num_busoff_err: 0
num_events:     30888
ECR:            0
fdf_rx:         27862
fdf_tx_req:     3016
fdf_tx:         3016

I am testing between a CubeOrange and a Pixhawk6X. I tested 1, 2, 4, 5
and 8 MBit (which are the only valid FD bitrates in our parameters)

Many thanks to Kai from Salient Motion for finding this issue and
providing the corrected timing table

Andrew Tridgell 0cfd9c2ed5 HAL_ChibiOS: don't consider a MAVCAN send failure as a send failure

Andrew Tridgell 33ebc83a68 AP_HAL_ChibiOS: disable CAN filtering except on AP_Periph 
this saves flash space and makes CAN forwarding for any bus without
reconfigure/reboot easy. CAN filtering is not useful in the main
flight controller firmware as we want to see nearly all packets
