TDA2EG-17: QNX OS support in TDA2E

Hi,

This question may be better addressed to QNX. I'm not aware of a publicly available TDA2x/TDA2E BSP from QNX, if there is one please provide a link or guidance

Both QNX 6.6 and QNX 7.0 both do have a publicly available BSP  for Texas Instruments Jacinto 6 (DRA74x and DRA75x) EVM, which is very similar device.

In terms of moving from QNX6.6 to QNX7.x, this can be accomplished by reading QNX's Migration guide.    When selecting the QNX OS version, please be aware that QNX SDP 7.1 is also available.

Regards,

kb

Very thank you for your reply.

Qnx6.6 tda2e BSP package,  we can't find a GPU driver.

If there is no relevant driver, the development difficulty and cycle will be very troublesome.

Do you have any suggestions about qnx6.6 GPU?

The GPU driver is distributed as part of the QNX Screen Package, which is a separate download from the QNX BSP.

Regards

Dear kb,

         We try to run QNX6.6 in JACINTO 6  ENTRY RSP/EVM by your guidance.  Here is the debugging information：

Hardware environment: JACINTO 6  ENTRY RSP/EVM

BSP:bsp_ti-j6entry-dra71x_evm_br-660_be-660_ti_rel_1_0

Startup mode of development version:  uboot + qnx-ifs

     When we try to run GPU related programs, "screen startup failed" appears. Please refer to the log at the bottom log for details。

   Can you take a look at the following questions? 

1. What‘’s the reasons for SGX INIT failure  and,  how to solve it?

2. Can I download to omap5 SGX DDK QNX and PVR_ Tools (QNX)  to test the GPU without 'screen'?  and How to?

3. What is  relationship between M4_display_link and QNX_screen?

4. Does Ti have any patches or user_guide for running and testing tda2e GPU on qnx6.6?

Thank you very much,kb

Hi Liping,

The J6 Entry BSP available on qnx.com includes a User Guide.  

http://community.qnx.com/sf/frs/do/viewRelease/projects.bsp/frs.texas_instruments_dra71x_jacinto.texas_instruments_dra71x_jacin_0 

The J6 Entry BSP was validated using the IPL as the bootloader, not Uboot,

In regards to the GPU error, please check if there is /usr/lib/graphics/XXX directory available for the J6Entry. 

Regards,

kb

Dear KB,

We also try to use IPL + ifs, and the result is similar to GPU error（Please check the below Log）.

Can you provide more suggestions to investigate the problem?  Thanks~

Hi Liping,

In regards to the GPU error, please check if there is a /usr/lib/graphics/jacinto6ECO directory available, and adjust the "screen -c" command accordingly.  

Logs above show  /usr/lib/graphics/jacinto6 is being referenced, this will not work with J6 Entry GPU.  The  /usr/lib/graphics/jacinto6ECO directory path needs to be used for the GPU to function on the J6Entry.

Thanks you KB~

and Where can we get the directory（/usr/lib/graphics/jacinto6ECO or jacinto6Entry）？
