Detailed Description

esp-hosted port header: UART transport buffer size.

Tag

[Ring 4 / PORT] {World: NS}

One of the ten port headers the vendored esp-hosted core includes by name (see docs/SOUP/esp-hosted-host.md). This project selects the full-duplex SPI transport, but transport selection is a preprocessor chain evaluated inside shared vendored files, so the UART header must exist with its upstream name and its one upstream macro.

MAX_TRANSPORT_BUFFER_SIZE

#define MAX_TRANSPORT_BUFFER_SIZE   (ESP_TRANSPORT_UART_MAX_BUF_SIZE)

Bytes framed in one UART transport packet.

Derived from the vendored ESP_TRANSPORT_UART_MAX_BUF_SIZE (1600). The UART transport carries the same esp-hosted payload header as the SPI one, so the frame size matches; only the pacing differs.

Note

Read-only build configuration.

Warning

Only meaningful when H_TRANSPORT_IN_USE == H_TRANSPORT_UART.

Example:

uint8_t *buf = malloc(MAX_TRANSPORT_BUFFER_SIZE);
