raiden00pl opened a new pull request, #20903:
URL: https://github.com/apache/nuttx/pull/20903
## Summary
Fixes in the nRF52/nRF53/nRF54L IEEE 802.15.4 radio driver:
- TX scheduling: five code paths decided independently when a waiting
frame may start, and lost frames or disabled the radio during an ACK; one
txnext() now owns that decision
- RX filter followed neither 7.5.6.2 nor the PAN coordinator rules:
beacons were dropped once macPANId was set, broadcast PAN ID frames and
source-only frames were dropped
- RSSI of a received frame was always 0 and LQI was the raw register value
- the radio interrupts ran at NVIC priority 0 above the critical sections,
their handlers call the OS
- nRF5340: the application core left the HFXO load capacitors untrimmed
unless it used the HFXO itself, so the network core radio was off frequency
## Impact
fixes for nordic IEEE 802.15.4
## Testing
nrf52840-dk, nrf5340-dk (net core), nrf54lm20-dk, nrf52832-dk with MRF24J40,
every coordinator/device pair: association, 50 direct, 30 indirect frames,
poll, expiry, re-association, energy scan, resources back at baseline.
