[U-Boot-Users] slow boot
Hi,
I am using a PXA270-based board with u-boot-1.1.2. I wonder if I could make the bootup process faster. I have measured the following times (with a stopper watch ...):
-Time to the first output on the serial console (baudrate: 115200): ~3 sec -Time to "Hit any key to stop autoboot (boot delay: 1s): ~5 sec -Time to "Starting kernel...": ~8.7sec
So I have delays after the messages: "Err: serial" and "Entry Point: a0008000". I have set "verify=no" in the environment. Any ideas how to make the boot faster? Thank you for your help!

Sounds as if your system is seriously misconfigured.
Where is your environment stored? Is this by chance in a EEPROM device?

The beaviour you see is not normal, but without knowing your hardware and your modifications to the code it is impossible to give any specific help.
As a general rule: version 1.1.2 is very old. Please update.

Another possibility is that your UART driver/hardware configuration (cache misconfiguration?) is not seeing the UART "Tx ready" flag properly so that every time a character is sent to the UART it polls the UART flag for the maximum time, making the serial output extremely slow.

No hardware knowledge, just speculating... gvb
