Hi!

I have installed the example RMakerSwitch after select RainMaker partition scheme and erase all flash.

But I can't make the code work, I'm always getting the error below.

How I can solve this problem?

Best regards.

@sanketwadekar will your PRs fix this issue?

[sanketwadekar]

These memory allocation issues are seen because the latest esp rainmaker c library is using heap_caps_calloc(), heap_caps_malloc() APIs for memory allocation. These APIs work fine in Rainmaker IDF examples. I'm not sure why it is breaking in Arduino.

[FernandoGarcia]

Hi!

Thanks for the attention.

Why the RainMaker partition scheme is available only under ESP32 Dev Module? I can't see it in ESP32 Wrover Module or Wrover Kit.

My board has 8 MB of FLASH the RainMaker partition scheme is suitable for this size?

Best regards.

@FernandoGarcia
Thanks for reporting this issue.
As I said earlier, the rainmaker c libraries are pre-built using config CONFIG_SPIRAM=y for esp32 target. Now, not all esp32 modules have PSRAM. So without even checking whether PS RAM is available, rainmaker is allocating memory on ext. ram. This causes memory allocation failures on chips which do not have PS RAM. Even if the module has PSRAM, and if it is not enabled in Arduino IDE "Tools" menu, the same errors will be seen.

Moreover, if you refer to this table, pin 16(in esp32 wrover kit) is used for accessing PSRAM but in the example gpio_switch is set to 16 which will cause memory allocation failures since PSRAM would become inaccessible.

Also, this memory allocation issue has exposed a few bugs in the Rainmaker Arduino libraries, which I will fix and will be available in the next release. Until then, you can use Arduino-ESP32 2.0.6 to build your Rainmaker projects. 🙂

Hi!

Moreover, if you refer to this table, pin 16(in esp32 wrover kit) is used for accessing PSRAM but in the example gpio_switch is set to 16 which will cause memory allocation failures since PSRAM would become inaccessible.

This type of conflict should be checked during the compilation for all features, no? Like a sanity check.

Regarding the partition scheme, here's missing the rainmaker option.

I don't know if I have to open a new issue for this.
