Enabling UART1 and tvp5150 on dm365 based custom design board

Hi,

We have purchased DM365 EVM board for our experiments. We have designed our hardware based on it.

We have used 1Gbit  nand flash. NAND1G-B2C.

Our board is having tvp5150 video decoder chip instead of tvp5146 for video input.

We have used UART1 for interfacing Gsm/Gprs modem, which is sim900.

We are usinng open source kernel from git. downloaded from TI site. The kernel version is 2.6.92-rc2-davinci. 

I have modified board-dm365-evm.c for our hardware. Basically i have 3 problems

  • How to get proper nand partition form new nand flash. The partitions remains same as DM365 evm board is with 2Gbyte ?
  • We have used GIO34 and GIO25 for UART1. We have also enable those pins using PINMUX registers as UART1_TXD and UART1_RXD. But when i run simple test code to check the UART1, it's not working. What are the steps to enable UART1?
  • tvp5150 driver is registered into the kernel but how to register it to vpfe driver, in board-dm365-evm.c, it registers to tvp5146/ tvp7002. So how to make it work to register a video driver?

 

Thanks and Regards,

Jagdish
