AM35x : Errata

Updated GettingStartedGuide for PSP 03.00.00.02

Current Limitation

• All data captured through TVP5146 signal path has a greenish tint for low to mid luminance levels due to a CbCr offset. CbCr offset is caused by ALAW compression of TVP5146 10 bit output into 8 bits prior to frame buffer.

Shiva Beta Application Board Hardware Modification (to change CCDC D0 -> D9 bit mapping)

• 8 MSBs of TVP5146 output should be mapped to 8LSBs of Shiva (AM3505/35017) CCDC/Camera interface since data formatter/lane shifter was removed from device hardware.
  • Remove R48, R49, R232, and R233 and map U8 outputs D9:D2 to D7:D0 through 22 ohm series termination resistors (dropping off 2 LSBs of TVP5146 output)
    • Connect U8 pin 13 -> pin 1 R232 or pin 4 R230
    • Connect U8 pin 14 -> pin 2 R232 or pin 3 R230
    • Connect U8 pin 2 -> pin 3 R232 or pin 2 R230
    • Connect U8 pin 3 -> pin 4 R232 or pin 1 R230
    • Connect U8 pin 5 -> pin 1 R233 or pin 4 R231
    • Connect U8 pin 6 -> pin 2 R233 or pin 3 R231
    • Connect U8 pin 8 -> pin 3 R233 or pn 2 R231
    • Connect U8 pin 9 -> pin 4 R233 or pin 1 R231

Shiva VPFE Register Setting Changes

• Change ALAW Configuration Register, 0x5C06004C bit 3, to 0 (disabled)
• Change CCD Configuration Register, 0x5C060054 bit 5, from 1 (10 bit) to 0 (8 bit)
• SYN_MODE Register, 0x5C060008 bit 11, should be set to 1 (Pack 8 mode)
