Re: [U-Boot] Not able to get the prints in the do_irq handler

Hi, balaji:

I am facing the typical problem relating to prints in the do_irq

handler of

versatile based u-boot. I dont know what is the problem. Though i am getting the prints normally in super visor context but not able to get

the

prints in the interrupt context. Please can you tell me if it is

possible.

Maybe i met the same problems as you met. When i turned on irq, added print in do_irq() handler, but no output. Traced by JTAG tool, found do_irq() had been run, and printf() was also run, but no output.

My platform had 512MB DRAM, so i changed to 256MB to report to Uboot code. Let Uboot know only 256MB DRAM exist. And the output is normal. Not have time to find the root cause.

My U-boot codebase is: 2013.04 official release version.

Best wishes,
