Board Support Packages

Network driver

The io-pkt networking stack has been replaced with the High-Performance Networking Stack (io-sock). Remove references to devnp-* drivers (io-pkt drivers) and use devs-* drivers (io-sock drivers) instead.

For additional required updates to the buildfile, see Modifying a BSP to support io-sock.

Adding flattened device tree (FDT) support (AArch64 only)

The option to use dtb=path to specify a flattened device tree blob (DTB) file when you start io-sock is no longer available. To adjust for this change, you need to update the startup library to support the -u option, which enables adding a FDT to the asinfo (Address Space Information) section of the system page. For more information, go to Startup.

After you have made the startup library changes, add -u reg or -u arg when you specify startup parameters in the buildfile. For example:

startup-imx8x-qm-cpu-mek -s -W -u reg

For more information, go to the Options for 64-bit ARM (AArch64) startups in the startup-* options entry in the QNX OS Utilities Reference.

The devc-sermx8 serial driver

For devc-sermx8, use -i to set the interrupt mode to event mode (0). For example:

devc-sermx8 -e -F -S -u 1 -i0 -c80000000 0x5A060000,257

Target-side command-line utilities

Some QNX OS command-line utilities that run on QNX OS targets have been replaced with toybox versions (see http://landley.net/toybox/about.html).

For instructions on how to enable toybox utilities, see the toybox entry in the QNX OS Utilities Reference.

For a full list of deprecated and discontinued items, see the QNX Software Development Platform 8.0: Discontinuation Notice.

Networking utilities

To provide network access, use a secure protocol such as SSH and SCP. For example, the following buildfile content starts the SSH server (/proc/boot/.ssh-server.sh), configures the ssh and scp utilities, and updates the PAM configuration (the /etc/shadow values need to be replaced with functional ones):

OpenSSL updates

The QNX cryptography library (qcrypto library) plugin for OpenSSL is updated from qcrypto-openssl.so to qcrypto-openssl-3.so.

Update the qcrypto library configuration file tags to use the updated plugin. For example:

[uid=0 gid=0 perms=0644] /etc/qcrypto.conf = {
openssl-3 tags=*
}

DHCP client

The DHCP client for QNX SDP 8.0 is dhcpcd. It also provides the IPv4 Link Local addressing and IPv6 Router Solicitation functionality that was previously provided by autoipd and rtsold, which have been removed.

Because dhcpcd can monitor interface states, you don't need to run it under ifwatchd. However, ifwatchd is still provided to support the configuration of static IP addresses.

For dhcpcd to start, you need to create /var/run in a persistent filesystem (e.g., Power-Safe filesystem). See Persistent filesystem.

Audio components

Currently, QNX OS does not support any audio functionality. Remove any references to audio components (e.g., io-audio, deva-* drivers).

[data=c] attribute setting

The [data=c] attribute setting that could be applied to all OS image executables is no longer supported.

Startup library

The startup library requires several changes to support QNX OS 8.0, including adding FDT (flattened device tree) support and configuring the CPU's virtualization hardware.

For details, compare the hardware/startup/lib directory of a QNX SDP 7.1 BSP with an appropriate QNX SDP 8.0 BSP.

Board-specific startup module

After making the startup library changes, make the following changes to the board-specific startup module in hardware/startup/boards/soc/:

• In hardware/startup/boards/soc/board_name/main.c, after calling alloc_ram() in main(), add the following call:

  hypervisor_init(0);

• For AArch64 targets only, in hardware/startup/boards/common.mk, add the following line:

  LIBS += fdt
