X-NUCLEO-53L8A1 with NUCLEO-F401RE on Ubuntu

[kgb]

Hello everyone,

I am very new to the STM ecosystem and don’t know much about it. I am using an Ubuntu PC and trying to work with the X-NUCLEO-53L8A1 expansion board and NUCLEO-F401RE.

There is a software package available for VL53L8CX to detect the presence of someone: "https://www.st.com/en/embedded-software/stsw-img042.html". I downloaded it along with the Linaro GCC toolchain from Linaro Releases. After running the Makefile and trying to start the application, I encountered the following error: "./spdkit: 1: Syntax error: Unterminated quoted string".  At first, I thought this was a command-line issue, but I suspect something else is wrong. Since the X-NUCLEO-53L8A1 communicates via I2C, I checked for available devices with: "sudo i2cdetect -y1".

However, no I2C devices were detected. I also noticed that my NUCLEO board is recognized in ST-Link mode, which might be preventing proper I2C communication(i am not sure !)

I’m a bit lost and not sure where to start troubleshooting. Most tutorials I found are for Windows.

Has anyone worked with this setup before? Any help would be greatly appreciated!

Hi 

From your description, sounds like you are trying to connect STM32F401+X-NUCLEO-53L8A1 to your Ubuntu system.

Normally we don't setup test environment as this for Linux test, 

• For HW, you need a Raspberry Pi instead of a STM32 board. then you need to connect X-NUCLEO-53L8A1 to Raspberry Pi by flying wire.
• For the SW, you can either use your Ubuntu system to set up the cross compile to Raspberry Pi code compilation or you can compile the code on Raspberry Pi directly.

I connect my L8 satellite board as in the enclosed document. (Sorry it's not a very good doc - just my notes.)

But I did cheat a bit. 

Notice that LPn is jumpered to ​J3-1V8 and the center pin. I needed to remove the jumpers on the other side of the board. (I needed a flat front.)​

But it does work a treat.
