Hi Robert,

Thanks for replying.
Can you kindly share below reference/location to cross compile some kernel or uboot:

  1. BBB defconfig file
  2. BBB toolchain.

The defconfig you can grab from here: zcat /proc/config.gz

or here: ti-linux-kernel-dev/defconfig at ti-linux-5.10.y · RobertCNelson/ti-linux-kernel-dev · GitHub

or here: bb-kernel/defconfig at am33x-v6.1 · RobertCNelson/bb-kernel · GitHub

Hi Robert,

I requested for upgrade i.e. let assume, i incorporated an additional module into kernel and the updating version by our own, so for this, lets see, i downloaded a fresh https://www.kernel.org let say linux-6.3.7 and latest uboot from https://source.denx.de/ then after downloading , what are the steps i need to perform to create a fully bootable card ?

Whats is`bb-u-boot-am335x-evm package ? It seems a uboot for am335 evm. How does this connects with BBB ?

Regards.

BBB uses an am335x, am335x_evm_defconfig in u-boot supports a lot of boards…

Dear All,

I want to have Linux PCIE device driver development from scratch to hands on for Network/Storage drivers. Can anyone suggest some beaglebone board with all supportive hardware ?

Regards.
Ankur

You would need to post a block diagram of the system you intend to build. Not sure what all the requirements are. For networking and storage that is in the context of the most common usage you should not need a custom driver.

36

The BeagleBone-AI64 has a M.2 E-key with PCIe/USB/SDIO, setup for WiFi BLE PCIe devices… Or if you want something else can order an E-Key adapter to any other PCIe style.
