- Tue Feb 02, 2021 8:49 am #90390 Hello to all,
I am new on this forum.
There is a strange problem with my esp8266. So far I have been unable to solve it.
when I boot here is what I get: "a load partition table error".
I dont know how to solve this problem. Here are the traces at the boot time:

load 0x40100000, len 7040, room 16
tail 0
chksum 0xfb
load 0x3ffe8408, len 24, room 8

chksum 0x12
load 0x3ffe8420, len 3336, room 8

chksum 0x33
csum 0x33

E (101) boot: Failed to verify partition table

I tried to re flash the partition table with the download tool rev 3.8.5 I got

test offset : 32768 0x8000
case ok

is stub and send flash finish

Seems it is OK but problem at the boot time.

Should I reflash other things ?
I hope you have a clue on what is going on
Thanks a lot
