While free firmwares are hard to write, some exist for very specific hardware (e.g. <a href="//www.arduino.cc/">Arduino</a>, <a href="//dangerousprototypes.com/docs/Bus_Pirate">Bus Pirate</a>) and sometimes, manufacturers can liberate firmwares running in their integrated circuits (e.g. <a href="//github.com/qca/open-ath9k-htc-firmware">ath9k_htc</a>). - However, it is not always possible to even replace those firmwares: some are loaded to the integrated circuit by the main CPU but some others are pre-installed in the circuit (in that case, they almost seem to behave like hardware) and cannot be updated to a free replacement. + However, it is not always possible to even replace those firmwares: some are loaded to the integrated circuit by the main CPU, but some others reside in separate storage from where they are loaded by that integrated circuit. + With separate storage, it can be difficult (to impossible) to update the firmware to a free replacement. </p> <p> <a href="images/freedom-privacy-security-issues/bad-modem-isolation.png" data-lightbox="current-situation" data-title="Bad modem isolation"><img src="images/freedom-privacy-security-issues/bad-modem-isolation.png" alt="Bad modem isolation" style="width: 250px; float: left;"/></a> |
