Fixed issues
| Reference | Issue | Fixed in version |
|---|---|---|
| 2972632 | Startup includes physical addresses 0x0 to
0x1000 to the
memory available to the operating system. However, these addresses are reserved by the firmware,
and their use by the operating system can lead to instability.
Workaround: Add -r 0,4096,1 argument to startup in the BSP buildfile. |
Build 290 (0.1.0.00290T202506261128L) |
| 2972632 | Fixed issue: bcm2711 startup adds firmware-reserved RAM to the system. | Build 290 (0.1.0.00290T202506261128L) |
| 2980062 | Fixed issue: When multiple i2c-bcm2711 instances were launched, each I2C transaction took a very long time. | Build 290 (0.1.0.00290T202506261128L) |

Issue tracking
Known issues
| Reference | Issue | Workaround |
|---|---|---|
| Not available. | This BSP enables watchdog with timeout value of 2500ms which may need to be adjusted. Please refer to the User's Guide for specific instructions on how to adjust the timeout value of watchdog timer. | None available. |
| 2998207 | The RPi4 retains the /dev/sd* entries and fdisk output for an inserted SD card, even after removal. | None available, though R/W operations still succeed after reinsertion. |
| 3005811 | When configuring the spi.conf file, invalid settings should result in the SPI driver returning an error and not starting. Bad values for the following settings instead result in the SPI driver starting, and returning a 0: bit_order, cs_delay, cpha, cpol, word_width, and clock_rate. | None available. |
Licensing and Resources
Licensing information
The QNX SDP licensing, packaging, and fulfillment model from the previous release has been carried forward to this release. That is, QNX SDP will be available in the QNX Download Center and QNX Software Center as a new product baseline. Additionally, the licenset agreements will include a few enhancements for clarifications but otherwise will remain unchanged.
Getting started with this BSP
We recommend that you read the Building Embedded Systems guide, which contains common information about working with all BSPs. This guide is available on the QNX Software Development Platform 8.0 documentation website.
This BSP includes prebuilt IFS images to ease initial board setup; however, these images might not contain the components most appropriate for your development environment.
To ensure your IFS image contains compatible components for your development environment, we recommend that you rebuild the IFS image on your host system.
