  "message": "examples: write the host cdc console over RTT when that is the console\n\nconsole_write() forwards what the attached CDC device sent back to the\nboard\u0027s console, and reached for board_uart_write() directly to stay\nnon-blocking. On a board whose console is the debug probe there is no UART:\nboard_uart_write() is a stub returning -1, so everything the device echoed was\ndropped, and the do/while loop retried a write that could never make progress\nand spun until more data arrived.\n\nSend it through SEGGER_RTT_Write() on LOGGER_RTT builds -- already\nnon-blocking in the default NO_BLOCK_SKIP mode, which is what the UART path\nwanted board_uart_write() for.\n\nThe retry is also bounded now. board_uart_write() is only documented to\nreturn the number of bytes sent, and the stubs disagree on how they say \"no\nconsole here\" -- lpc40 returns -1, apm32f0xx returns 0 -- so the loop cannot\ndecide from the return value alone when to stop. It gives up after 10 ms\nwithout progress instead, which no draining console ever hits, and keeps the\nnegative return as a fast path so a stub UART does not cost that wait on\nevery read.\n\nThe RTT header include lives in board_api.h so any example can reach it; the\ninclude path only exists when LOGGER\u003drtt defines LOGGER_RTT.\n\nhost/cdc_msc_hid now passes on ea4088_quickstart, whose probe (LPC-Link2) has\nno VCOM: the CDC echo round-trips through a CH340 with TX-RX shorted.\n",
