Hi,
I just found another potential problem with the MCF532x/537x port.
In speed.c, there is currently no handling for CONFIG_MONITOR_IS_IN_RAM. Additionally, the order of the SDRAM controller workaround and re-enabling RAM has to be changed like this according to the freescale errata document:
/* software workaround for SDRAM opeartion after exiting LIMP mode errata */ *sdram_workaround = CFG_SDRAM_BASE;
/* * Return the SDRAM to normal operation if it is in use. */
I am currently trying to work out the SDRAM self-refresh code so I can contribute it here.
(With the modifications from the last email, I have parts of the new coldfire u-boot already running. However, I still have problems with this PLL code - probably because I am running from RAM at the moment- and with env_init, of which I did not yet further investigate the latter.)
Regards, Wolfgang
