ES1371 on Walnut Platform

Dear all, I tried to bring up a ES1371 audio card on Walnut evaluation board. It is recognized successfully and the content of registers are dumped and find to be the same as that found on PC. But it doesn't work because I can't receive any interrupt from the card to show the completion of DM

question on using correct in/out functions

Hi: We use a mpc860t based board (2.4.20 kernel) and the addresses beyond 0xf000 are io-remapped. In driver space, to access memory mapped devices beyond this address i have some simple routines like in8/in16/in32 and out8/out16/out32 which basically use val = *addr or *addr = val kind of acc

driver for CyberPro 5202 Display Processor

Hi, A google search on cyberpro 5202 chipset drivers on linux did not produce any significant result. I may have to write the drivers for this, so any input is welcome. Any help/hints on other cyberpro 50xx chipsets are also welcome. Thanks, om. ** Sent via the linuxppc-embedded mail list. See

mpc8xx memory mapped 16550 extrenal uart driver

Thanks for your reply, I am using serial.c from denx 2.4.4 kernel, for creating a module called serial.o for my 16550 external uart. I made the modifications suggested by you. However, what I do not understand is - what is TTY2_MAJOR? Why is it required? what device node am I supposed to create?

Status of MPC5200 ???

Hi there, I wonder to which extend Motorola's MPC5200 is supported by now. I know www.denx.de has a tree in its CVS server. Is everything supported yet? What about BitKeeper? Will there be support for this processor in the 2.4 series? Which compiler do I need to use its floating point capabil

8xx uart driver problems

Hi, I have been investigating a problem with the 8xx_io/uart.c driver included in Denx's 2.4.4 kernel. We have a system where under certain circumstances, the MPC855's SCC locks up when a large amount of noise is received by it. The problem occurs just after pppd opens the SCC port. I can preven
