[U-Boot] u-boot hangs on panda board after some time
On TI panda board, stay in u-boot and do nothing in 30 minutes, then try to get mmc info or reset, u-boot will hang.
Bellow is the error log: -- Panda # printenv
baudrate=115200 bootcmd=if mmc rescan ${mmcdev}; then if run loadbootscript; then run bootscript; else if run loaduimage; then run mmcboot; fi; i bootdelay=3 bootscript=echo Running bootscript from mmc${mmcdev} ...; source ${loadaddr}

sounds like the core timer logic is broken for whatever omap part is on there -mike

That is correct, once the timer reaches 0xFFFFFFFF it reloads with 0xFFFFFFFF and gets stuck there. I did a patch that was never accepted late last year. On more careful consideration my patch was also broken but in different ways.
