Tool/software: Linux

My issue very closely mirrors the following post, but the solution there did not work for me:

https://e2e.ti.com/support/arm/sitara_arm/f/791/p/572042/2099047

I'm trying to install Python 3.x on the AM572x EVM. To do so, I've followed all of the summary steps here:

http://processors.wiki.ti.com/index.php/Processor_SDK_Building_The_SDK#Build_Steps

...with the exception that I used tisdk-rootfs-image instead of arago-core-tisdk-image.

I then ran the following with the below results:

~/tisdk/build$ MACHINE=am57xx-evm bitbake python3

Afterwards, I moved the resulting python3* .ipk files from arago-tmp-external-linaro-toolchain/deploy/ipk/armv7ahf-neon/ to a USB drive. After mounting the drive on the AM572x EVM, I tried installing and got results as shown:

root@am57xx-evm:/media/usb_drive/python3_ipks# opkg install --offline-root . python3-core_3.5.1-r1.0_armv7ahf-neon.ipk
Not selecting python3-core 3.5.1 due to incompatible architecture.
Unknown package 'python3-core'.
Collected errors:
* opkg_install: Cannot install package python3-core.

When I check the opkg architecture configuration:

root@am57xx-evm:/media/usb_drive/python3_ipks# opkg print-architecture
arch all 1
arch any 6
arch noarch 11
arch armv5hf-vfp 16
arch armv5thf-vfp 21

arch armv7at2hf-vfp 51
arch armv7ahf-neon 56
arch armv7at2hf-neon 61
arch am57xx_evm 66

The target is running off of an SD card created using the TI Processor SDK 03.03.00.04 create-sdcard.sh's default image.

Why am I not able to install these packages? Thanks!

Hi,

Can you check the bellow announcement and see if there are any other dependencies, that you didn't take care of?

Best Regards,
Yordan

Thanks for the quick response. I don't see anything that I need to take care of there. (But then, I don't really recognize any dependencies shown on that announcement at all, so maybe I'm missing something.)

Here's a bit more info:

I have the same problem when trying to install .ipk files using the "man-pages" recipe built the same way.

Here's example output from using "opkg info":
