Hello,
I have custom board based on TI AM3892 processor. We've managed to run Linux + Arago FS on board through the agency of E2E Community and espesially Pavel Botev. The board's design is very similar to DM816x/CA816x/AM389x EVM but there are some valuable differences. Now we are trying to run HDMI.
I have a questions about syslink at first:
There is two processors on EVM: cortex A8 and MSP430F2132. On our board we have A8 only. As said in wiki pages syslink library is a funcional layer controlling the inter-processor communction between Cotex A8 and Cotex M3(http://processors.wiki.ti.com/index.php/DM816X_C6A816X_AM389X_VPSS_Video_Driver_User_Guide_PSP_04.00.00.12) (here is misspelling in your wiki page, Cotex instead of Cortex). Since I have only one processor on my board, do I need syslink module to run HDMI?
I tryed to load HDMI related modules without the syslink and I failed. What can be a reason of the issue?
During linux startup there are following error message, also same message we receive when trying to load vpss linux kernel module manually.
BUG: Your driver calls ioremap() on system memory. This leads
to architecturally unpredictable behaviour on ARMv6+, and ioremap()
will fail in the next kernel release. Please fix your driver.
