First question asked Welcome!

Hello Everey-one,
Facing issue with the Work Flash Bus Error Response from few of the ECUs which were using Traveo-I MCU. Kindly help me to check the below scenario.

May i know what can cause DED bit set while accessing Work Flash, How can we test the scenario by injecting a fault in Traveo-I and reproduce DED bit set.

Hi @Chaitu_Badri 

Please provide more details - 

  1. Before facing double bits error, single bit error(ECC correctable error) also should be observed. Are you observing that?
  2. What condition are you using the device in? e.g.) super high temperature over the Spec?
  3. What are the experiments done for WORK Flash? e.g.) repeat Program & Erase over 100k cyc?
  4. Are you reading from Programmed bits? (for WORK Flash, it cannot read 1-data from just Erased bits)

Regards.
