We now replace TC233L with TC223L. It is found that can communication is available after burning the bottom layer. After burning the app, the product does not work.
Please help analyze the potential factors that may lead to this problem, and evaluate the workload of software modification to solve this problem .
The key parameters for each variant of TC23x and TC22x series is available in the following docs. Please compare for each of your device and check if the differences are handled
You mentioned that "CAN communication is available after burning the bottom layer. After burning the app, the product does not work". Does it mean that CAN is working fine after replacing the device but when the complete application is flashed it is not working ?
If yes, please check if there are any Traps or unintended resets occurring in the System because of this change.
