Running pre-built image from SD doesn't do anything... #1

Open br548 opened 6 years ago

br548 commented 6 years ago

I followed the guide all the way until Step 8 under "Run the pre-built image from SD".

I am using minicom to try and read in the boot process but it doesn't return anything at all. Im not sure if it's a configuration issue with minicom or if the project build is broken.

My end goal is to create a program that writes to a serial port using petalinux but I can't even seem to get the basic, pre-built .bsp files working properly just for testing purposes.

Specs: Zybo Z7-10 I am plugged in via PROG UART micro-USB and Im all but certain the USB is at ttyUSB1. SD card was formatted properly with GParted. One 3GB FAT32 partition and one 55GB ext4 partition.

Any help would be greatly appreciated.

Minicom can be tricky... It likes to enable hardware flow control by default. Try pressing Ctrl-A then Z to get to a help menu. Then find the menu where you set Hardware flow control and disable it (Maybe 'O'?). You should be able to set the default to not use flow control from that menu too.

Yeah I have that disabled too. Again, I have all of the right setup...the board just does nothing after the SD is put into it. I should be seeing a terminal print out in minicom right?

I'll add that I am pressing the PS-SRST button after the SD card is inserted into the board.

Am I supposed to put the rootfs.cpio file onto the ext4 partition? To me, it seems like the board has nothing to grab other than the BOOT.bin and image.ub files. and that doesn't seem like it can do anything.

Hey,

I'm running into the same issue right now. Just copying the prebuild BOOT.bin and image.ub files on a fat16 or fat 32 partition on the sd card. Connecting the PC via USB to the zybo board. But I can't even see the ttyUSBX device. And the rx and tx LEDs on the board stay dark. Did you by any chance find a solution to your problem?
