Hello,

DCSM Password Update Issue

  1. After checking the red box in the following image, update the password with dual encryption of pswdlock and JTAGlock

0xA2135CDF

0x4D7F0120

0xB2F5A6D5

0xCB777B13

Update to

0xA2135CDB

0x4D7F0120

0xB2F5A6DB

0xCB777B1B

  1. Compile and generate the dcsm.asm file and dcsm.cmd file after updating the password.
  2. Copy the latest dcsm.am and dcsm.cmd files to the app's included files. Bootload has no dcsm file. (The first version of the bootload and APP both included the dcsm.am file and the dcsm.cmd file. At that time, CCS was used to burn the bootload code and APP code separately. Later, in order to burn the bootload and APP code simultaneously in UniFlash software, the dcsm file in the bootload was deleted to burn them simultaneously.)

  1. Use UniFlash to burn the. out file with the latest password. Simultaneously burn the bootload.out file and APP.out file.

  1. Burning failed, error message as shown below. May I ask how to solve this problem? Or where is the problem with the operation?
