-This document describes how to upload the cx2341x firmware to the card.
-
-How to find
-===========
-
-See the web pages of the various projects that uses this chip for information
-on how to obtain the firmware.
-
-The firmware stored in a Windows driver can be detected as follows:
-
-- Each firmware image is 256k bytes.
-- The 1st 32-bit word of the Encoder image is 0x0000da7
-- The 1st 32-bit word of the Decoder image is 0x00003a7
-- The 2nd 32-bit word of both images is 0xaa55bb66
-
-How to load
-===========
-
-- Issue the FWapi command to stop the encoder if it is running. Wait for the
-  command to complete.
-- Issue the FWapi command to stop the decoder if it is running. Wait for the
-  command to complete.
-- Issue the I2C command to the digitizer to stop emitting VSYNC events.
-- Issue the FWapi command to halt the encoder's firmware.
-- Sleep for 10ms.
-- Issue the FWapi command to halt the decoder's firmware.
-- Sleep for 10ms.
-- Write 0x00000000 to register 0x2800 to stop the Video Display Module.
-- Write 0x00000005 to register 0x2D00 to stop the AO (audio output?).
-- Write 0x00000000 to register 0xA064 to ping? the APU.
-- Write 0xFFFFFFFE to register 0x9058 to stop the VPU.
-- Write 0xFFFFFFFF to register 0x9054 to reset the HW blocks.
-- Write 0x00000001 to register 0x9050 to stop the SPU.
-- Sleep for 10ms.
-- Write 0x0000001A to register 0x07FC to init the Encoder SDRAM's pre-charge.
-- Write 0x80000640 to register 0x07F8 to init the Encoder SDRAM's refresh to 1us.
-- Write 0x0000001A to register 0x08FC to init the Decoder SDRAM's pre-charge.
-- Write 0x80000640 to register 0x08F8 to init the Decoder SDRAM's refresh to 1us.
-- Sleep for 512ms. (600ms is recommended)
-- Transfer the encoder's firmware image to offset 0 in Encoder memory space.
-- Transfer the decoder's firmware image to offset 0 in Decoder memory space.
-- Use a read-modify-write operation to Clear bit 0 of register 0x9050 to
-  re-enable the SPU.
-- Sleep for 1 second.
-- Use a read-modify-write operation to Clear bits 3 and 0 of register 0x9058
-  to re-enable the VPU.
-- Sleep for 1 second.
-- Issue status API commands to both firmware images to verify.
