SDCARD example issues

Mohsin455 — Tue, 24 Jan 2012 23:17:07 GMT

Hi All,

I am using K60N512 Tower kit and MQX3.8. I am trying to use the SCARD example. I have enabled the following flags

#define BSPCFG_ENABLE_ESDHC 1

When I run the code I get the following screen and I can read the contents of the SDCARD using dir command.

The problem is when I try to do a read I get the following message.

SD card demo

Can anyone please let me know how to do read/write using shel commands ?

Thanks,

Mohsin

Hi,

Can anyone please let me know if they are having similar issues ?

Along with the read problem, I am having the following issues

I am using microSD card. When I copy the files (e.g. test.txt) from Windows XP into the microSD card and display it using the shell program I am seeing .TXT.

I tried formatting it from the shell and the format went ok but still I am having the same issues. Can anyone please advise whats going on ?

Thanks,

Mohsin

If you can look at the sectors on the SD card you may be able to interpret why the effects are seen (confirm whether the file entries are really written like that or whether there is some obvious corruption etc.).

Assuming this is possible, there is a guide to understanding the data here: http://www.utasker.com/docs/uTasker/uTasker_utFAT.PDF

You can also try a reference binary here: http://www.utasker.com/SW_Demos.html which will allow you to read the content and also reformat the card (K60 Tower assumed) and see whether it then operates correctly (it allows interfacing similar to DOS and also managing files via FTP). This would distinguish whether the problem is at the SW or HW level.

Hi Mark,

Thanks very much for your reply. I will try loading the binary but the diference is I am using SDHC interface. I am getting similar resuls on the TWRK60N512 and custom board so I was wondering if there is any restriction to use microSD card (i.e size, make etc).

Hi Mohsin

SDHC and SPI modes should give same results on almost all cards (size is not important and manufacturer shouldn't be either - uSD card can be inserted into an adapter to fit full-size SD card sockets); some new high speed card may no longer support SPI mode (although I didn't encounter such a card yet) so SDHC should be less troublesome in any case.

It is also useful to have a range of test cards (different memory sizes, from different manufacturers) for comparison should unexpected results be obtained.

Regards

Mark

Hi Mark,

I have tried downloading the uTasker binary using CW -> Flash File to Target and I am getting the following message

Hi Mohsin

I just tried with CW10 to see whether I could reproduce the problem but it worked OK (although it does take quite a long time - about 2 minues).

The console output that I had is below, as comparison.

I also made a screen shot of the Flash Programming dialog. It looks a bit different - I am using CW10.1 (version 1.0.0) and you may be using a newer version.

Also the code started correctly (once you get it loaded, use the serial menu at 115k or also connect to the board via Telnet - default IP = 192.168.0.3 - and go to the SD card menu. Then you will have a DOS-like interface).

This seems to be a CW problem (or a target configuration one) so it may be workth asking in the CodeWarrior forum what is going on.

Regards

Mark
