Hey hi,
I am using AM3715 EVM module and i want to configure Gpio pins so can you tell me the complete procedure as I am fresher and i am working on the same.
You told that it's in uboot folder but where this folder is located in MMC card or pre built binaries folder?
Also can you describe the procedure to configure the UART port as I am using them for interfacing other modules.
Regards
Sharlin Kothari
Sharlin:
Not in MMC card, that will be binary!
Check out the uboot source code, in that specific files to your board AM3715 EVM!
Which gpio pins want to use, configure as gpio and then request and use it!

Hi Santosh Vastrad
Thanks for your help but can you suggest me any website or link which helps me to configure GPIO pins(How to configure and basic commands for configuration)
In Uboot source code:
check beagle.c file
functions:
1) beagle_identity:
2) misc_init_r:
which pin want to control request, and set 0 or 1:
also see beagle.h file for configuration
MUX_VAL(CP(PIN_NAME), (IDIS | PTU | EN | M4)) /*PIN_NAME*/\
PIN_NAME : refer usermanual of AM3715
Hi Santosh
thanks for your help.
Right now I am syncronizing the repo again and redownload the source code as soon as i complete with that i will be working as per your guidance.
Then also if some problem occurs then i'll put a query to this post.

While compiling the U-boot I found the following error on my terminal and I am stuck as I can't move forward for compiling the other things:

Hi Santosh,
I am working on JORJIN ATGN441-JS 11330-25 processor having core processor AM/DM 37X & TPS 65950 based COMPANY CUSTOMISED BOARD.
I have compiled all the binaries successfully and make the MMC card using them still my board cannot be booted and the android screen is not coming up.
Please help me regarding any end notes you can provide for the jorjin processor and any other help.
Hi
Please help me regarding the above post of mine as I am stuck and I can't move ahead in my project.
In your board, Nand flash is there?
If Yes , try to boot from it, by flashing binaries onto the Nand flash!
