Hi,
I'm trying to read certain configuration register (SDR0_PINSTP) using u-boot setdcr/getdcr commands (I run 1.1.4 u-boot on AMCC PPC440EP Yosemite board). First thing I do is setting this register's offset (0x40) in the SDR0_CFGADDR (0xE) DCRN:
=> setdcr e 000e: 00000020 ? 40 000e: 00000040 ? =>
However it doesn't look having any effect:
=> getdcr e 000e: 00000020
And when I read SDR0_CFGDATA (0xF), I get register with offset 0x20 (SDR0_SDSTP0) as expected:
=> getdcr f 000f: 8570828a
Before I start to debug do_setdcr() function, may be somebody knows this issue and it was even fixed?
Thanks,
Leonid.
