器件型号： TDA4VM
我们面临类似的问题和 TI 提供了修复,我们想确认是否同样的修复将适用于 J721S2 11.01.00.04 也,请再次分享应用的确切补丁,因为有多个迭代修复

Brijesh Yadav 请您 确认
我相信你想要标签 Brijesh Jadav 。
你好 chenthil saminathan
是的、您可以禁用 LDC 节点的 wdTimer 来解决问题（在 SDK 11.02 中默认禁用此功能）

嗨、Gokul
我们应用了此修补程序、该修补程序在旧的 TT 中共享

以上变化就足够了
尊敬的 Chenthil：
抱歉、没有收到您的问题、Gokul 的回答是完全禁用 LDC WDG、但在补丁中、我为 LDC 添加了 128KCycle 选项。 因此、即使添加了 128KCycle 选项、 完全禁用 WDG 也足够了。
此致、
Brijesh
感谢 Brijesh Jadav 我们应用了 128KCycle 选项 并 完全禁用 WDG ,希望这应该是可以的
是的、 chenthil saminathan 、 在这种情况下禁用 WDG 是可以的。
