Otpvondoiats opened a new pull request, #19478:
URL: https://github.com/apache/nuttx/pull/19478
## Summary
This is a patch for the AMP architecture. RK3506 CPU 0 and 1 run Linux,
while CPU 2 runs Nuttx.
## Impact
1. The ARM A7 chip is based on the QEMU bundle.
2. Add an accessor function to drivers/serial/uart_16550.c in the 16550
serial port driver to expose the internal console device object pointer.
- Because the shared GIC caused the core to not receive UART interrupts,
the board switched to polling to receive characters. Polling requires calling
the upper-level `uart_recvchars()`, which necessitates accessing the driver's
internal console `uart_dev_t`. Therefore, this commit specifically added an
accessor to expose it. TX and the per-core private PPI timer are unaffected;
only the shared SPI RX has this issue.
3. The NuttX client cannot access the flash memory; the control terminal is
on the Linux side.
