Other Parts Discussed in Thread: HALCOGEN
Hi,
i have a problem with the FEE unit of the Lanchxl2 TMS57012.
I want to save the data of the example code of HalCoGen 4.05.01 into the eeprom and read it out after a restart of the controller.
The read and write operations work and while the mcu is active i can read the correct stored data.
But when i want to read the data directly after a restart, the storage is empty.
What am i doing wrong?
