Known issues
For common QNX Software Development Platform issues that may impact this BSP, see the QNX Software Development Platform 7.1: Release Notes.
This BSP has the following known issues:
USB devices may not be detected when booting from SBL. (Ref# J2935436)
Workaround: In hardware/startup/boards/j7200/evm/hw_init.c, unlock CTRLMMR partitions 1 and 2 at the beginning of hw_init(void). It is recommended that at the end of hw_init(void) any paritions that were locked be locked again and to remove any other locking and unlocking in hw_init.c.
- OSPI driver devf-j7-ospi does not support PHY and UDMA on J7200 (Ref# J2899677)
Workaround: Do not use OSPI with dac, phy and dma options.
- USB driver devu-hcd-cdns3-xhci.so does not support USB3.0 on J7200 (Ref# J2900085)
Workaround: Start USB driver with nousb3 option to use USB2.0 only.

To ensure that you pick up the same components from your
development environment, we recommend that you rebuild the IFS
image on your host system.
Included in this BSP are prebuilt IFS images that are provided as convenience for you to quickly get QNX Neutrino running on your board, however these prebuilt images might not have the same components from your development environment. |
