Mbedtls using external memory failing

[shaun-mzj]

Hardware:

Board: esp32
Core Installation version: 1.0.5-rc6
IDE name: Arduino IDE
Flash Frequency: 40Mhz
PSRAM enabled: yes
Upload Speed: 921600
Computer OS: Mac OSX

Description:

I've built the latest release candidate of the code manually and have enabled the following flag: CONFIG_MBEDTLS_EXTERNAL_MEM_ALLOC which causes the following error when accessing a web server:

[E][ssl_client.cpp:36] _handle_error(): [start_ssl_client():210]: (-30592) SSL - A fatal alert message was received from our peer
[E][WiFiClientSecure.cpp:132] connect(): start_ssl_client: -30592

However if I switch mbedtls to use internal memory it can connect fine. Is there something else which needs to be done for the mbedtls library to use external memory?

[shaun-mzj]

I've got a simple example which tries to load an ini file from a server via HTTPS which works if using internal memory but fails when switched to use external. The sdkconfig we used to build with is also below as well

This used to work until the lets encrypt cert was updated and at the same time it was switched from x3 to r3, maybe this causes the issue?

We've also added a component to idf which loads the file via HTTPS and called it from Arduino and it has the same issue. Calling the component from an esp-idf built program and it works. Could you please advise on why the same code when built via esp-idf would work but when built via Arduino would fail?

[me-no-dev]

Are you saying that when using Arduino as IDF component it is failing, but when using only IDF it does not? Other than that, Arduino does not have the flag for external RAM set

[shaun-mzj]

I'm using the esp32-arduino-lib-builder and have enabled the external memory option in the config file. When running the output that repo produces from the ./build.sh command mbedtls seems to have issues. However when running the same mbedtls code via edp-idf it works fine.

Disabling external memory and running ./build.sh and using that output with Arduino works fine, for some reason enabling external memory breaks it.

[me-no-dev]

hmm... since the lib builder is in reality "Using Arduino as IDF component", what happens if you change main.cpp in it with your Arduino sketch and run make flash monitor ESPPORT=[your-uart-port] ESPBAUD=921600 after ./build.sh?

[shaun-mzj]

Replacing main.cpp with the test idf code and running as above works fine

[me-no-dev]

Are you sure that you copied the resulting release from ./build.sh to your other Arduino install? ./tools/copy-to-arduino.sh?

[shaun-mzj]

I'm building on Linux but running Arduino on Mac so am using a different script to copy but am copying the newly build one over. If I wasn't copying it over disabling the external memory flag for mbedtls and copying again wouldn't make it work?

[me-no-dev]

if something is not copied over properly, your change will not apply. Are you sure that all is copied over?
https://github.com/espressif/esp32-arduino-lib-builder/blob/master/tools/copy-to-arduino.sh#L17-L22

Are you using the same version of esp32-arduino on the Mac? (BTW I use/develop the lib builder on a Mac. Maybe you can try that?)

[shaun-mzj]

Thanks, I'll try building on Mac and running the same script

Yes we did everything. That you mentioned probably like 50 iterations. back and forth.

At the last i have another code in which we just use the static mbedtls

mbedtls_memory_buffer_alloc_init( memory_buf, sizeof(memory_buf) );

Using this.

Interesting thing.

When i use internal ram it works fine.

But if i use psram malloc it crashes.

[akshar001]

I'll post that code here too.

It's little messy up but it will do our job.

For that i needed to uncomment #define tag from esp_config in mbedtls component esp-idf folder

//#define MBEDTLS_MEMORY_BUFFER_ALLOC_C

I thought if i just allocate psram memory in before everything it might solve the problem but still same issue.

[akshar001]

So if use this

// unsigned char alloc_buf[80000];

it works fine.

[akshar001]

but when we use this

alloc_buf = (unsigned char *)heap_caps_malloc(80000,MALLOC_CAP_SPIRAM);

problem.
