simple_ota_example pb with ESP-IDF 4.0

[adesandr]

Hi,

I'm trying to run the simple_ota_example.
All seems good (certicate handskake, upload, etc), but at the end, I face with a tls problem.

I (3134) tcpip_adapter: sta ip: 192.168.1.45, mask: 255.255.255.0, gw: 192.168.1.1
I (3634) example_connect: Connected to ADesandre

E (7384) esp_image: invalid segment length 0xffffffff
E (7394) simple_ota_example: Firmware upgrade failed

Any idea ?

Thank you in advance for your help

Regards.

Hi,

I've tried to run the native_ota_example, and i've obtained the same issue :

Has indicated in the exemple, i'm runnint the hhtp server with 'openssl s_server -WWW -key ca_key.pem -cert ca_cert.pem -port 8070'

my version off openssl is 1.1.1a 20 nov 2018.

If you have any idea ?

Regards.

You have 2 situations here.
1. problem with secured connection

E (7125) esp-tls: read error :-76:
E (7125) TRANS_SSL: esp_tls_conn_read error, errno=Socket is not connected

2. i doubt you binary file has on 15421 bytes, so what you are downloading and flashing?

Hi,

Thanks for your answer.
I’ve solved this issue.
All my previous tests were done using Git Bash and his embedded ming64 distribution.
I’ve tried to install msys2 to do the test using OpenSSL 1.1.1e, and both simple_ota and native_ota work fine.
Maybe a problem with the OpenSSL version in Git Bash, but i can’t explain why.

Thats possible. Maybe default size of certificate is the issue. esp32 is accepting 2048 bytes key IIRC, but doesnt accept 4096.
