What exactly do you mean by interrupt multiplexing?
Oh, It is mean u-boot providing an interrupt management to manage lots of interrupts from the device. Like linux kernel. So forgive me for asking such unclearly question make you confused.
U-Boot is probably not the optimal environment to process "lots of interrupts". If you need to do more complicated stuff, boot an operating system. U-Boot is just a boot loader.
Ok, Thanks for you help. I will try to using the polling method to inplement the device driver.
OK.
P.S. I can't use my company's email to subscribe the mailist. please check the address pwu@jadechip.com, is it been blocked by the mailist system?
Maybe SourceForge is blocking it, I don't know. Ther eis no special setup in the mailing list configuration itself to block any addresses. But SF is really fastidious with there requirements.
