mbedTLS Memory Allocation in SPIRAM (AFR 202012.00)

Hi,

I am trying to allocate mbedTLS memory in SPIRAM. I changed mbedTLS memory allocation scheme from “Internal memory” to “External SPIRAM” in the menuconfig. I was unable to create TLS connection. It raised following log…
326 33343 [Network Manage ] ERROR: Handshake failed with error code :
327 33343 [Network Manage ] TLS_Connect fail (0x1, xxxxxx-ats.iot.us-east-1…)
328 33343 [Network Manage ] [ERROR][NET][333430] Failed to establish new connection. Socket status: -1.

Please be note that I was successfully connected to AWS IoT Core when used Internal memory. [Note: xxxxxx placed intentionally for this post]

SPIRAM Configuration:

[Note: I disabled SPIRAM workaround code, though I am using ESP chip revision 1. iram0 segment overflowed if I enable SPIRAM workaround code]

I appreciate your time and feedback to resolve this. Thanks :slight_smile:

The issue has resolved. If anyone use PSRAM (SPI RAM) with esp32 chips silicon revision 1, SPIRAM workaround code MUST be enabled.

Thanks!

Thank you for taking time to report back.
