Dear,

Could you please let me know how I can make the UART print speed for TensorFlow Lite Micro-Speech example?

The default speed is 115200, but I want 921600 baud rate.

Thank you.

You will need to edit the BSPs located in the make/downloads/AmbiqSuiteSDK/boards_sfe folder. Edit the BSP corresponding to your board. look for a UART configuration structure

Thank you for your quick comment.

However, it didn’t work if I change the file which is make/downloads/AmbiqSuiteSDK/boards_sfe/edge/bsp/am_bsp.c.

I did modify lines from 115200 to 921600 in the file.

Please let me know if you were mentioning different BSP file that I need to modify.

Thank you.

It is not working after regenerate boards_sfe/edge/bsp/gcc/bin/libam_bsp.a.

Thank you so much for your help.

/* typo correcting */

It is “now” working after regenerate boards_sfe/edge/bsp/gcc/bin/libam_bsp.a.

Thank you so much for your help.

Ahh, glad to hear it. Nice work determining that you need to re-build the BSP static library!
