I’m using a custom carrier board with a DSI to HDMI connector according to V1.0 of the Toradex DSI-HDMI Adapter. We started with this carrier board using a Verdin Mini SOM. Now we switched to a Plus module and still want to use the same carrier board with the connector for the V1.0 Toradex DSI-HDMI Adapter. (The newer adapter V1.1 is using another connector…)
I know from the compatibility table that the Verdin Plus module is compatible to the V1.1 DSI-HDMI Adapter only. But I’m wondering if this is just due to different connectors or if there is a reason why the V1.0 should not work together with a Verdin-Plus module? Are there maybe any specific dev-tree settings needed in order to make it running?
When comparing the datasheets from V1.0 and V1.1 of the adapters, they look very similar except for the board-to-board connector they use.
When trying to apply the dev-tree overlay for the lt8912 I get the following errors during bootup:
[ 0.741120] imx-drm display-subsystem: bound imx-lcdifv3-crtc.0 (ops lcdifv3_crtc_ops) [ 0.749131] imx_sec_dsim_drv 32e60000.mipi_dsi: version number is 0x1060200 [ 0.756141] imx_sec_dsim_drv 32e60000.mipi_dsi: Failed to attach bridge: 32e60000.mipi_dsi [ 0.764418] imx_sec_dsim_drv 32e60000.mipi_dsi: failed to bind sec dsim bridge: -517, retry 0
I’m using Toradex BSP 5.6.0-devel-202202 with an Verdin Plus V1.0 Module and a custom carrier board.
Thx in advance!
