Other Parts Discussed in Thread: AM3892, AM3894
We are making our customized system from TI8168 EVM.
And we used DDR2 memories for managing captured images from FPGA FIFO buffer.
Actually our customized TI8168 board doing capturing buffer and transmitt datas via Gigabit ethernet.
We spent a lot of time to make it boot up our board with TI 8168 board PSP source in TI-EzSDK.
TI-EzSDK version is 5.00.00.56 and, PSP is 04.00.00.07(kernel 2.6.34)
We have tried to boot it up and wanted watch "THE EYE".
But we still have problem. we are thinking problem is DDR memory initializing.
Please watch following dialgram.
(AM3892 Data sheet DDR2 Interface schematic)
We set double 16bit1GBit DDR2 memory at EMIF0. and set one 16bit 1GBit DDR2 memory.
Sure we have tested memory in CCS v4. (in test of CCS v4, it successfully worked !)
But u-boot doesn't boot.
By checking J-TAG debugger, it stops when PC indicated 0x2008C address.
Does anybody knows why it happen? and similar problem ?
If it need to contains GEL or DDR memory setting source codes, we will attach in here.
** AND **
1. How could we have stores RAW image datas with HDVPSS ?
Is there any sample source code? or datas?
To do it, what we need ?
2. We want to store datas via external FIFO by Synchronous Read Burst Access.
How can we read 4-word or 8-word ?
