Super ContributorHi,
Thank you for contacting Intel community.
Per my understanding, you are using design example from below?
Also,
If your design is sensitive to the PCIe boot-up requirement, Intel recommends that you do not use the direct-to-application feature.
Intel recommends that you set a fixed start address and never update the start address during user mode. You should only overwrite an existing application configuration image when you have a new application image. This is to avoid the factory configuration image to be erased unintentionally every time you update the start address.
Can you try this? Let me know your feedback.
Regards,
Aiman
Occasional ContributorHi
Thanks for your response.
Yes, I am using design example from below link
We are using same example design & driver.
"If your design is sensitive to the PCIe boot-up requirement, Intel recommends that you do not use the direct-to-application feature."
- can u please help how to disable direct-to-application feature?
Note: Configuration Mode is disabled from tool
"Intel recommends that you set a fixed start address and never update the start address during user mode"
- Yes, we are not changing start address and trying to update only application image
"You should only overwrite an existing application configuration image when you have a new application image. This is to avoid the factory configuration image to be erased unintentionally every time you update the start address."
- We are using master image jic file and updated through onboard blaster.
- We try to replace the application image(either 1 or 2) by using same master image(ru_auto) rpd file.
We are getting read back data error error after 100% Erase & Write Completed

Step1 : Do you want to download the application image to FLASH?
(Please input 'y' or 'n' to select, and press ENTER to go on):y
Step2 : Please input start and end address of application image downloaded to FLASH.
(You could get below information from *.map file, and input here.)
(Warning: Please use start address 0x0 if you are downloading factory image!!!)
START ADDRESS :0x04000000
END ADDRESS :0x5568FFF
Step3 : PLease input program file directory.
(For example: /home/rsu_over_pcie/user/ru_auto.rpd)
/home/jetson/GRL_C2V/A10_Flash/vel_image/app2c_auto.rpd
Info : Download application image into Flash, file size is 22450176 Bytes, start address is 0x4000000
