Part Number: DRA829VXEVM
Hi everybdoy ,
I m on DRA829 evm , working on Linux .
now I would like to access some GPIO with a scope , moving these pins during code so to run measures on timing , jtters etc
do you have any example on how to move a GPIOs on the board , a easy one to connect to a probe ? it is not trivial having pinmux etc .
any example code ?
thank you
best regards
Carlo
Hi Carlo,
The available test points on the EVM can be found in the EVM schematics document, by searching on "TP". The location of the test point on the EVM, can be found in the EVM Board document, by searching for the desired test point.
For example, searching on TP within EVM schematics for J721E EVM Common board, TP100 is shown to be hooked up to WKUP_GPIO_52.
Searching on TP100 within the J721E EVM Common Board, Board document shows the location of the test point on the Common Board.
Another candidate to consider would be TP45, WKUP_GPIO0_6.
