  2. 問題 ARM使用TI供電模組時,無論任何電壓皆無法播放數位相框程式,DSP會無法順利啟動(見下圖),但若改執行其他非DSP處理的工作(ex:madplay)或改為DSP使用此TI供電模組時則都可正常執行。

  3. 解決辦法 將DSP1之供電模組轉接給ARM使用,DSP1則改由外接之電壓調變模組供電。 修改DSP端之firmware,使其可控制外接之電壓調變模組。

  4. Firmware修改 • Firmware內之程式包含控制Philip_PMIC與TI_PMIC,目前PAC Duo上已確定使用TI之模組,所以只需修改TI_PMIC部分的程式碼即可。 • 目前程式已修改並測試完成,由DSP1控制外接之第三組電壓調變模組可正常運作,但此版本之firmware不可再控制原先DSP1所使用之PMIC。

  5. Android上之相框程式改良

  6. Any Questions or Suggestions?
