[参考译文] CODECOMPOSER：如何在使用 J-link 编程器时擦除所有闪存

卡佐拉

我不确定此功能是否可用。

当使用 XDS110启动调试会话时、我可以看到名为 cc26x2_XDS.gel 的 GEL 文件被加载到调试器中。  其中包含 MassErase 函数。

menuitem "CC13x2_CC26x2"
/**
 * \brief    This function issues a board reset before erasing the device flash.
 *           This function disconnects from target after completion.
 *           NOTE: If CM4 DAP is locked, make sure to disable "Custom configuration"
 *                 from all sub paths in the device's target connection file (.ccxml).
 */
hotmenu MassErase()
{
    GEL_TextOut("Initializing.\n", "MassErase()");
    _isMassErase = 1;

    // Disconnect from target. This must be done for each module in the device debug sub-system hierarchy.
    DisconnectIfConnected(); // Cortex
    GEL_EvalOnTarget("<parent>", "DisconnectIfConnected()", 1); // DAP (Cortex' parent)
    GEL_EvalOnTarget("<parent>", "GEL_EvalOnTarget(\"<parent>\",\"DisconnectIfConnected()\", 1)", 1); // Icepick (DAP's parent)

    // Do board reset
    GEL_TextOut("Issuing Board Reset.\n", "MassErase()");
    GEL_AdvancedReset("Board Reset");

    // Reconnect to Icepick
    GEL_EvalOnTarget("<parent>", "GEL_EvalOnTarget(\"<parent>\",\"ConnectIfDisconnected()\", 1)", 1);

    // Issue mass erase from Icepick and disconnect
    GEL_EvalOnTarget("<parent>", "GEL_EvalOnTarget(\"<parent>\",\"IP_CC26xx_CHIPERASE = 1\", 1)", 1);
    GEL_EvalOnTarget("<parent>", "GEL_EvalOnTarget(\"<parent>\",\"DisconnectIfConnected()\", 1)", 1);

    // Workaround on engineering devices. Disconnect and reconnect for chip erase to take effect.
    ConnectIfDisconnected();
    DisconnectIfConnected();
    _isMassErase = 0;

    GEL_TextOut("Mass erase complete.\n", "MassErase()");
}

使用 jlink 时、会加载不同的 GEL 文件 cc26x2_jlnk.gel。 它没有等效函数。  查看该函数、它似乎使用 ICEPick 来执行批量擦除。  JLink 可能无法使用 ICEPick 来实现这一目的、因为它是 TI 特定的调试 IP。  我需要在连接团队中进行回放以进行评论。  我怀疑这也会影响 CCS 提供的闪存选项。

此致、
