All,
has anyone set up the DDR-II controller on a Freescale MPC8343A without ?
without what?
typo - sorry.
As far as I can see there are only DDR-I boards from Freescale.
The MDS can do ddr2:
U-Boot 1.3.2-00097-gbc508d1 (Mar 25 2008 - 10:47:17) MPC83XX
Reset Status: Software Hard, External/Internal Soft, External/Internal Hard
CPU: e300c1, MPC8349E, Rev: 30 at 528 MHz, CSB: 264 MHz
Board: Freescale MPC8349EMDS
I2C: ready
SPI: ready
DRAM: 256 MB (DDR2, 64-bit, ECC on)
...
Hmmm ... I get :
U-Boot 1.3.2-00075-gc5f497a-dirty (Mar 25 2008 - 19:55:00) MPC83XX
Reset Status: Check Stop, External/Internal Soft, External/Internal Hard
CPU: e300c1, MPC8343, Rev: 31 at 399.999 MHz, CSB: 266 MHz
Board: Matrix Vision mvBlueLYNX-M7
I2C: ready
SPI: ready
DRAM: cs0_bnds = 0x0000000f
cs0_config = 0x80844102
DDR:bar=0x00000000
DDR:ar=0x8000001b
256 MB
It's a 32-Bit DDR-II without ECC.
2 Chips are soldered to CS0, i.e. no EPROM present.
Since I expect something like "(DDR2, 32-Bit, ECC off)" and nothing
happens there is obviously something wrong with my memory setup.
Is this reasonable ?
Or am I simply missing a board specific "board_add_ram_info" ?
Am I assuming right that your info string "(DDR2, 64-bit, ECC on)" comes
from spd_sdram ?
Are there any patches not yet posted to handle this ?
should work, only diff I see is that the 8343 is 32-bit only.
Kim
I'll dig a little deeper now and ask more questions tommorow.
Thanks for your help !
regards,
Andre
