Driver sd need updating dating a new guy
Follwing are the Hyper Terminal windows showing card detection (One window shows baudrate as 38400, that was while testing for higher clock speeds, current code still uses 19200 baud and 8MHz internal clock of Mega32). 'create File' function replaced with write File, which looks for the filename first, if the given file name doesn't exist then it creates new file and writes data, but if the file already exists, then it opens it and appends the entered data. - A bug removed which was giving error related to use of 'LONG' - : 1 raw data block (512 bytes) takes 4.15ms for reading or writing (123.37 KBytes/s) at current 4 MHz SPI clock rate. The microcontroller is AVR ATmega8 or ATmega32 running at internal clock.MAX232 is used to interface the circuit with PC for monitoring the data.I started with raw data transfer, sending some data to any block of the micro SD, reading a block of it, reading and writing multiple blocks, erasing multiple blocks. I used RS232 for viewing the data read by microcontroller from SD card. Similarly, to write data to card, the data was fed thru Hyper Terminal, by typing some text.
If you use option 0, 1 or 3, you may have to reformat the card before using the FAT32 routines.2010-01-19 [Bug 9872] Driver 'sd' needs updating - please use bu linux-scs bugzilla-daemon 4.2009-07-18 [Bug 9872] Driver 'sd' needs updating - please use bu linux-scs bugzilla-daemon 5.2008-05-05 Re: [Bug 9872] Driver 'sd' needs updating - please us linux-scs Kay Sievers 12.2008-05-04 [Bug 9872] Driver 'sd' needs updating - please use bu linux-scs bugme-daemon 13.
