MQX Software SolutionsのトピックRe: USB Memory Stick Testing https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185764#M3189 <HTML><HEAD></HEAD><BODY><P>We have had a great deal of grief over this problem as well. What we found is that the speed of the USB Flash Drive is the deciding factor. The software consistently fails on very fast drives and always works on slower drives. The definition of slow and fast is open, but fast for us was about 30% faster than the slower drives. We have tried several drives and the ones that work for us on our in-house board are from SanDisk, and are the cheap ones from Costco 4G, 4 for 17$ on a card.</P><P> </P><P>What I believe is the problem is that the MQX scheduler interrupts and gets between the USB transfer at a byte level and the transfer fails on a missed response. We have seen similar issues with the i2c driver where the ACK was missed because of the RTOS scheduling interrupt. This was verified by the MQX people in the development team in Europe. This was more prevalent in MQX 3.7 than 3.8. I don't think we have seen the i2c timeout in 3.8 as yet.</P><P> </P><P>This problem makes it very difficult to deliver a product to a customer base that will use their own flash drives at some point. The entire product can be seen as unreliable or faulty. </P></BODY></HTML> Thu, 03 May 2012 03:21:10 GMT Cdn_aye 2012-05-03T03:21:10Z USB Memory Stick Testing https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185753#M3178 <HTML><HEAD></HEAD><BODY><P><SPAN class="Apple-style-span" style="color: #000000; font-family: Arial; font-size: 11px; line-height: normal"><STRONG>This is a place holder for feedback on all the USB sticks that are tested with MQX to ensure maximum compatibility.</STRONG><BR /><STRONG>1) Please post top USB Memory Stick Vendor for your region that need to be tested.</STRONG><BR /><STRONG>2) Please post the make/model/description of working and non-working USB sticks that you have tested.</STRONG></SPAN></P><P> </P><SPAN class="Apple-style-span" style="color: #000000; font-family: Arial; font-size: 11px; line-height: normal"></SPAN><H2>A.

What we found is that the speed of the USB Flash Drive is the deciding factor. The software consistently fails on very fast drives and always works on slower drives. The definition of slow and fast is open, but fast for us was about 30% faster than the slower drives. We have tried several drives and the ones that work for us on our in-house board are from SanDisk, and are the cheap ones from Costco 4G, 4 for 17$ on a card.</P><P> </P><P>What I believe is the problem is that the MQX scheduler interrupts and gets between the USB transfer at a byte level and the transfer fails on a missed response. We have seen similar issues with the i2c driver where the ACK was missed because of the RTOS scheduling interrupt. This was verified by the MQX people in the development team in Europe. This was more prevalent in MQX 3.7 than 3.8. I don't think we have seen the i2c timeout in 3.8 as yet.</P><P> </P><P>This problem makes it very difficult to deliver a product to a customer base that will use their own flash drives at some point. The entire product can be seen as unreliable or faulty. </P></BODY></HTML> Thu, 03 May 2012 03:21:10 GMT https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185764#M3189 Cdn_aye 2012-05-03T03:21:10Z Re: USB Memory Stick Testing https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185765#M3190 <HTML><HEAD></HEAD><BODY><P>Grief is a good way to put it.  I haven't seen problems with the canned example applications that come with MQX, but in real applications where there is a lot going on, problems with the USB drives happen frequently.  So I, too, am suspicious it has something to do with other peripherals interrupting the system, context switching, etc. We stayed on 3.7, we had consistent problems on 3.8 reading files from a USB stick on startup.  We are using the 5125 board.  For us two things usually happen, either the USB stick stops working all together and we have to pull it out and re-insert it to get it to work again, or we will see a string of corrupted data in the files we are writing out.  We really need this fixed.</P></BODY></HTML> Thu, 10 May 2012 02:29:35 GMT https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185765#M3190 dwillett 2012-05-10T02:29:35Z Re: USB Memory Stick Testing https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185766#M3191 <HTML><HEAD></HEAD><BODY><P>We are not only seeing some USB drives that fail, but a significant difference in speed when opening a file. A few of the USB drives that we tried open the file in 8-9 sec. Other take ~40-60 sec to open the same file. No clear relation to USB speed or density of the drive. </P></BODY></HTML> Sat, 12 May 2012 08:01:38 GMT https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185766#M3191 LANCO_M4 2012-05-12T08:01:38Z Re: USB Memory Stick Testing https://community.nxp.com/t5/MQX-Software-Solutions/USB-Memory-Stick-Testing/m-p/185767#M3192 <HTML><HEAD></HEAD><BODY><P>Is there today a solution to add by ourself new USB stick to MQX ?
