Firmware v2.19.0

tpi v1.5.1 → v1.6.0: the check that caused all of this is gone.

Firmware v2.19.0, 9 September 2026. Every item below is the repository's own changelog entry, taken apart; the whole entry is a click away under each one.

Changed

• tpi v1.5.1 → v1.6.0: the check that caused all of this is gone.

  The whole entry

  Three releases in a row carried attempts to make firmware install resolve a version correctly against the board's cached listing. The listing lags a release by up to half an hour, so firmware check would print install it with: tpi firmware install <v> and the next command would reject it. v2.17.0's attempt was inert; v2.18.0's worked by waiting up to three minutes.

  Both were the wrong shape. The resolution existed because of a comment claiming the board would otherwise fail "in the middle of a download". Measured: the daemon answers 400 in 0.48 s with tpi-selfupdate: cannot fetch SHA256SUMS for v9.9.9, before any download, staging nothing. There was nothing to protect against.

  So the listing now informs the confirmation line and cannot refuse, and the board — which is what downloads the image — decides. On a version that exists nowhere: 140 s and a possibly-wrong refusal before, 1 s and the board's own message now.

Fixed

• tpi firmware list --refresh could confirm that a release did not exist. It waited 60 s for a poll, then gave up and printed the previous listing with nothing said, indistinguishable from a current one. Polls measured on this board took 74 s, 78 s and 140 s.

  The whole entry

  Now four minutes, it says when it gives up, and list prints how old the listing is on every run — the daemon had always sent that, and the client discarded it.
