- JC 01:56 PM Software Development: RE: Using WKUP_UART0 in Linux Space
- Holden, TI wants to know if you are using the "VPAC/ISP camera functionality on your AM62A7". Presumably to determine if you need the dm_edgeai firmware or if you can get away with just the normal "ipc_echo_testb_mcu1_0_release_strip.xe...

As you noted in your email, the DM firmware is baked into the tispl.bin u-boot file. Linux doesn'... - Hi,
I am having some difficulty bringing up a serial port that utilizes WKUP_UART0 pins. From what I understand, it is typically reserved for DM logging and is unusuable in Linux until it is disabled. I have disabled the UART log for ...

- RD 11:44 AM Software Development: RE: Uart issue in Am62P
- Hi Jonathan,
The issue was in the code. We have a function that returns an int, but the application was crashing within that function when running on the AM62P with Debian OS. However, it works fine on the AM62A BSP.
I suspect the ...

- Thank you, that would explain it. We ended up setting the pin regardless of the current state. It was an easier change for us.

- JC 06:05 PM Software Development: RE: Can't read state of output GPIO pins
- At least for the AM62x, Pins that need to be read, must be pinmuxed as PIN_INPUT*. The only difference between the PIN_OUTPUT and PIN_INPUT #define is whether the input buffer is enabled.
- Hi,
On an AM62x we have a gpio pin (/dev/gpiochip2, line 10) muxed as an output pin. Our application checks the state of this pin to see if it is in the desired state before setting it if needed. Unfortunately the pin state is always ...
