Hello Espressif Team,

Does anyone has any idea regarding issue which i have put into last few comments with details? Because we are completely blocked due to that issue is faced at customer end.

Let me know if anyone has faced and recovered that issue from software side.
Regards,

No clue, but what may help: can you dump the flash and do a binary compare against a known-good flash to see what changed?

I have already did that thing earlier but didn't find anything means everything is fine.

Still let me check again with some more devices and will let you know.

Hi All,

I am also facing the same issue
"I (183572) esp_image: segment 0: paddr=00110020 vaddr=3f400020 size=2fcf4h (195828) map
I (183652) esp_image: segment 1: paddr=0013fd1c vaddr=3ffbdb60 size=002f4h ( 756)
I (183662) esp_image: segment 2: paddr=00140018 vaddr=400d0018 size=c9828h (825384) map
I (183932) esp_image: segment 3: paddr=00209848 vaddr=3ffbde54 size=035dch ( 13788)

I (183962) esp_image: segment 5: paddr=0020d234 vaddr=40080400 size=1d02ch (118828)
E (184002) esp_image: Checksum failed. Calculated 0x8b read 0xff"

PS: a) I am using the test bench setup, with power supply.
b)This is happening only for file sizes 1MB+, a file size less than 700KB was upgraded successfully

In case someone has any breakthrough on this so far, Would highly appreciate the response asap on this.
Best Regards,
Pradeep

Hello,

I think it may be problem for power supply fluctuation due to which it is failing at your end but we didn;t found any exact root cause for the same.

Because we are using device with inverter power supply in which we are facing issues randomly.

Problem found - it was our power supply - not handling the peak currents - thanks for your help
Hello Imtiaz and Espressif Team,

I just want to know that how it is related to power supply? can you please describe things little bit more? Because we are facing this issues into multiple places where solar solutions are installed and ESP32 module is getting power from Invertor only.

So, We are little bit confused like is it due to power supply issue or something else which we need to identify.
