Installing the IAP software on a PC
When all the items mentioned above are present, install the software on a PC as follows:
•Extract the Trident EXSDK package (EXSDK.zip) into C:\Trident\Bin.
•The IAPWriter6.exe file is now inside the Bin folder.
Programming the Flash IC
The
•Turn on the TV set, enter SAM mode > IAP. The TV is now in the IAP mode.
•Connect the PC to the TV via the
•
•Check that these parameters are set correctly:
DEVICE | STM29W400DT |
MPU Start Address | 080000 |
MPU End Address | 0FBFFF |
Buffer Start Address | 000000 |
Buffer End Address | 07FFFF |
Note: The device depends on the Flash IC used.
•Select File > Load, and select the .bin file to be programmed to the Flash IC.
•Select File Type “Binary”.
•Select “Write Device”.
Note: If there are no errors reported, the programming is successful.
Note: Sometimes, an error message may appear. Please try a few times if this happens.
Note: If you encounter any problems, contact your local support desk.
5.5Error Codes
5.5.1Introduction
The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right.
When an error has occurred, the error is added to the list of errors, provided the list is not full or the error is a protection error.
When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained), except when the error is a protection error.
To prevent that an occasional error stays in the list forever, the error is removed from the list after 50+ operation hours. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them.
5.5.2How to Read the Error Buffer
Use one of the following methods:
•On screen via the SAM (only if you have a picture). Examples:
–0 0 0 0: No errors detected
–6 0 0 0: Error code 6 is the last and only detected error
–9 6 0 0: Error code 6 was first detected and error code 9 is the last detected error
•Via the blinking LED procedure (when you have no picture). See next paragraph.
•Via IAP.
5.5.3How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “CLEAR ERRORS” command in the SAM menu.
•With a normal RC, key in sequence “MUTE” followed by “062599” and “OK”.
•If the content of the error buffer has not changed for 50+ hours, it resets automatically.
5.5.4Error Codes
The function of error codes is to indicate failures in the TV set. In principle a unique error code is available for every:
•I2C device error.
•I2C bus error (for every bus containing two or more I2C devices).
•Protection error (e.g. +8V protection or Horizontal protection).
•Error not related to an I2C device, but of importance (e.g.
