Hello everyone,

I tried to run CardInfo.ino example project from the SD library and it turns out the following error:

#error Architecture or board not supported.

This is really weird because on an another computer it's run fine.
Furthermore the console tells me that there are more than one SD library.
Anyone can help me please?

Regards,
Vincenzo

There is no CardInfo.ino in the SD library examples. You are running something from another architecture.

[per1234]

All recent versions of the Arduino IDE do architecture-based library priority inversion. This means that the library with the best library.properties architectures value match with the selected board will be used. The SD library bundled with this package specifies the architectures value esp32:

arduino-esp32/libraries/SD/library.properties

Line 9 in 1289f4b

architectures=esp32

So, as long as you correctly install the package, that library will have priority over other installed SD libraries which provide a wildcard match (such as the standard Arduino SD library), or an architecture mismatch.

I suspect you have not correctly installed the ESP32 package (similar problem to #20). I recommend you to use the Boards Manager installation method, which will insure it is installed correctly:

Hi @lbernstone , thank you for your reply.
I took the example from the arduino IDE. However if I run it on another computer, not my personal laptop, it works fine also on ESP32 board.

Regards.

Hi @per1234 , thank you for your reply.
I'm going to check the issue you reported. Is it possible a missmatch between the toolsuite version for esp32 that I have on laptop and the pc in lab?

Regards.

Hi @per1234 ,

I installed the board manager following the link you had suggested in the precedent post. I have the same error as before. Below there are what I read on the console

#error Architecture or board not supported.

As I suspected, the problem was caused by an incorrect manual installation. Your architecture folder is named "eps32". This causes the Arduino IDE to consider the architecture of all the boards in this package to be "eps32", which does not match the specified architecture "esp32" of the SD library at C:\Users\crist\Documents\Arduino\hardware\espressif\eps32\libraries\SD (the library you want to be using). That causes the standard SD library at C:\Users\crist\Documents\Arduino\libraries\SD to be used instead. The reason is that library specifies a wildcard in its architectures field and a wildcard architecture match has priority over an architecture mismatch ("esp32" vs. "eps32").

I installed the board manager following the link you had suggested in the precedent post.

If so, then it looks like you have a manual installation at C:\Users\crist\Documents\Arduino\hardware\espressif\eps32 in addition to the version installed via Boards Manager, which is installed to a different location on your computer. You should remove the invalid manual installation by deleting the C:\Users\crist\Documents\Arduino\hardware\espressif\eps32 folder.
