    Thanks for the information about reflow.

    Could you help me with the problem i described in the post TMS320F28035 EEPROM EMULATION

    DearSupplier,

    I developed a digitally controlled power supply using TMS320F28035.

    I'm using the Sector D of the Flash memory to emulate an EEPROM, in order to store calibration data.

    We have already done a mass production lote with 1500 units, and the EEPROM emulation works fine.

    Now we are producing a new lote of this product and we are facing some problems with EEPROM emulation.

    I'm using CCS3v3.

    The DSC can be programmed using the On-Chip Flash Programmer. However when the product is under operation and the Flash_Erase function is activated the DSC stops working and stays locked.

    After that i can repeat the programming process using the On-Chip Flash Programmer, so it seems that the memory is not permanently damaged or locked. But when the Flash_Erase function is used during run time the same behavior happens.

    I checked the memory behavior when  the Flash API functions are activated.

    The defective devices does not show a pattern, some device present the problem with the Flash Erase function and some others with the Flash Program function.

    Replacing the DSP the system works with the same firmware.

    The marking on the device is shown below:

    TMS320 980
