I did make the changes but I'm having problem reading from the MMC card (Getting Data Timeout) , At the moment I'm polling for the status without using irq, and that seems to work for configuring the card and reading manufacturer information like date, serial number etc. mca_vsn : 03 cmdclass : 1F5 tacc_clks: 00 tacc_ns : 4C4B400 max_dtr : 1312D00 read_blkbits: 9 capacity : 1003520 Manufacturer ID = 0000049A HW/FW Revision = 0 0 Product Name = MMC Serial Number = 0000049a Month = 12 Year = 2004 My question is it passible to do that without having to enable irq and using interrupt handler? Thanks
