[U-Boot-Users] Flash write crash on MPC8548CDS
1.3.2-rc1-gb6f29c84-dirty crashes on the very first attempt to write in Flash. After that it gets back to the prompt and _ALL_ subsequent writes work just fine. Only the very first one fails.
Looks like something is not initialized properly. Before I start digging does anyone has a fix for it? This is quite new platform for me so it could take time for me to come up with a fix...
Here is what happens on the very first Flash write attempt (original config with no changes, stock MPC8548CDS with SW2[1..2] set to "off-off", was "off-on" out of the box for booting Freescale's U-Boot 1.1.something from alternate Flash.)

How did you program u-boot into the flash?

With "tft xx xx; cp.b xx xx xx" :)
It _ONLY_ fails on the first attempt. Crash is _NOT_ fatal so system returns to U-Boot prompt then you do the second attempt that succeeds. And all consecutive writes work fine.
And initially I wrote new U-Boot with the original 1.1.something from Freescale that works OK in that respect.
