scripts/sd_put.sh <file> [card path] sends a file (by default into /updates, for Update from SD) without taking the card out. The serial driver drops bytes once its receive buffer is full, so the transfer is stop-and-wait: 1 KB chunks, each acknowledged once the Storage Service has written it, into a 2 KB receive buffer. The device checks the SHA-256 before renaming <path>.part into place, and gives up after 5 s of silence or a card job that never returns. FileReceiver holds the logic, with 12 host tests. About 55 KB/s: 1.6 MB in under 30 s. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT
