Q) Serial Baud Rate(Speed) change to higher rate in SPARKFUN EDGE with Applo3 SDK

Development Boards

Dear all,

As I know, the edge board uses baud rate as 921600 bps during flashing, and then change the baud rate to its operational baud rate which is 115200 after booted-up when I use “make bootload”.

Q) Can I change its operational baud rate from 115200 to higher rate such as 460800 or 921600 bps by changing the BSP and the source codes?

If then, please let me know which BSP or source codes should be changed.

Thank you.

Dear,

I updated the rate “115200” in below source codes to “921600” and then rebuild the bsp, it worked. However, I don’t know if both files should be changed. Thank you.

Hi kcoh777

You should not need to change the baud rate in the file ‘apollo3_evb/bsp/am_bsp.c’

It should be sufficient to simply change the value in the SparkFun Edge bsp ‘SparkFun_Edge_BSP/bsp/am_bsp.c’

P.s. have you tried using the updated BSPs and other tools?
