Arria 10: Remote Update may brick FPGA and Factory Fallback won't work

Hello, we have observed some critical failures when doing tests with various potential error scenarios concerning a remote Update of the FPGA bitstream in the attached SPI Flash device. We could re...

Hi Xiaoyan,

What I did is to place the application image in flash memory shifted by 1-10 Byte (Manually induced error scenario).
- e.g. expected Application image addr: 0x01000020, actual start position in flash 0x01000018.
- So in the described case, I expect a CRC error, since the image is missing its first 8 Bytes.
Yes. in the Application Image I am not asserting the RU_nRSTIMER signal, but the Factory image fallback didn't happen
- I am using the Remote Update Intel FPGA Avalon IP
- I am not performing any writes to RU_RESET_TIMER (0x5 Register) nor to RU_WATCHDOG_ENABLE (0x2 Register)

best regards

Fabian
