Vybrid USB Loading Utility

rod_k — Fri, 28 Jun 2013 23:48:23 GMT

Is there a Windows-based utility program for USB (Serial Loader) that can be used to download a boot image programming application (for on-board NAND Flash) into the on-chip RAM? The app would handshake with the PC to obtain a boot image for the NAND device (parallel, not QSPI), then program the NAND, so the next time we reset, the image is loaded from NAND. We have the jumpers on our Vybrid demo board set to boot from NAND Flash, but there is no boot image in the device. We believe that (based on the documentation, Figure 19-1 of the Vybrid RM), the high-level on-chip Boot ROM flow will drop into "Download and Authenticate Image Using USB/UART" mode. We are wondering if this serial loader/programmer application exists already from FSL, or do we have to create our own. Thanks in advance...

Hello All, I was checking this internally, sorry for not posting a follow up.

RossMcLuckie this is what I mentioned on our call, could you help providing your thoughts?

Thanks,

If you are familiar with our iMX products you may have used the MFG_Tool, with is what you describe. We are currently working on a Vybrid version of this. We have been given an internal delivery date for this as the end of August, so I would suggest assuming end of Q3 as a realistic customer delivery, we will release it as soon as we possibly can.

Will you be releasing a beta version for the Vybrid before the end of

August?

How similar to the iMX MFG_Tool will it be? If we study the documentation

for the MFG_Tool, will this be applicable?

Thank you,

A beta release is more likely the end of August schedule, hence the reason I suggested assuming end of Q3 for a customer release, right now I have no more detail than what I have given you already.

The Vybrid version will be a “lightweight” version of the iMX, so will be more restricted in its operation, but the basic principle should be the same.

How about beta version release?

Will it be released in a few days or not?

I am now using JTAG ICE to download the program but it is not easy and simple. I want serial downloader for Vybrid.

Unfortunately progress on the MFG_Tool for Vybrid is stalled for the time being, it was started and progress made, unfortunately the assigned people were unable to complete the work in the planned timeframe, so at this time we are assessing the outstanding effort and working on filling the resource gap to complete the work, I can not give you any indication of the time frame at the moment.

I will try to update this thread when we have updated plans.

Hi RossMcLuckie

Do you have an update on the progress of this tool?

Thanks

Martin

Re: Vybrid USB Loading Utility

RossMcLuckie — Wed, 16 Oct 2013 11:11:14 GMT

Hi Martin,

Sadly the update is only more of the same I'm afraid, we had resources assigned on this but unfortunately they were unable to complete the task before they left, since then we have struggled to identify alternate available resources. We have continued to push for this and emphasised the importance to our customers, I have recently heard alternate resources are now evaluating the work that has been carried out to date and what remains to be done.

At this time I'd be reluctant to give a date as we have been very poor on this so far, it will be released as soon as it is ready, but I do not see that happening in the short term, I would like to think it will be resolved by the year end, but I'm not able to commit to dates at this time.

Apologies for the continued delays

Ross

It is easy enough to use hidapi to get communications working with the Vybrid in Serial-USB. HidAPI supports Windows, Mac, FreeBSD and Linux. Most other HAB serial loader documentation is the same on the Vybrid. For example, I am migrating IMX25 code and the command structure is identical with a smaller allowed peripherals in the DCD. See chapter 19.8 of the Vybrid manual for more on the Serial-USB protocol.

Here is a hacked up version of hidtest.c,

The alpha and beta releases have been posted on the Vybrid extranet site, hopefully this should signal a public release early in the new year.

Just wondering if there is any new information about when this utility / tool will be ready / released.

Thanks.

Re: Vybrid USB Loading Utility

RossMcLuckie — Wed, 29 Jan 2014 17:48:29 GMT

At this time I have no further updates to give on this, I believe there are plans to review what is next for the Vybrid version of the Mfg_tool, one possibilty is the current beta version will become the final production release version, any update to the situation will be added here.

Thanks

How is the progress on MFG_Tool for Vybrid going?

Btw, I almost succeeded in developing my own tool loading program image to memory. Sending data to device using SDP WRITE_FILE command worked fine. However, after doing JUMP_ADDRESS command it doesn't execute correctly and execution goes back to boot ROM. Any ideas how to debug it?
I was using DS-5 for the time being so I was able to see that program was actually loaded to memory where I wanted.

Many thanks!

It is most likely a swapping issue, the JUMP_ADDRESS seems to be big endian. The command sets use a mixture of both endian-ness and I don't think what endian things are is documented.

         u_char hid_report[64];

         memset(hid_report,0,sizeof(hid_report));

        // report code

         hid_report[0] = 1;

        // command type

         hid_report[1] = 0x0B;

         hid_report[2] = 0x0B;

        // address is big-endian

         hid_report[3] = (address >> 24) & 0xFF;

         hid_report[4] = (address >> 16) & 0xFF;;

         hid_report[5] = (address >> 8) & 0xFF;;

         hid_report[6] = address & 0xFF;

Re: Vybrid USB Loading Utility

paweltryfon — Wed, 26 Feb 2014 08:45:57 GMT

Thank you Bill.

I tried both big and little endian for ADDRESS field and you are right it should be big endian. I still don't see my program starting. Is there any initialization/register settings required I am not aware of?

I am able to see that my program loaded correctly and when I jump to the entry address from DS-5 debugger it works fine. It seems that I just have some issue with doing JUMP_ADDRESS command. Any hints regarding how to debug this will be much appreciated.

Many thanks,
Pawel

Re: Vybrid USB Loading Utility

The latest information on the Mfg_Tool is we expect to have an official release end or March, early April, depending how well testing goes. This will be the beta version, plus support for NAND on the Tower board.

As for your own version, are you maintaining the 16 byte (17 including report ID) SDP format, most of the fields are not relevant for the JUMP_ADDRESS command so you can put whatever data you want, but suspect they will still be needed, can simply be all 0's.

Do you see a Report3 back from the device, unless you see this then you are not successfully sending a correctly formatted JUMP_ADDRESS SDP.

Regards

Ross

Re: Vybrid USB Loading Utility

paweltryfon — Wed, 26 Feb 2014 15:13:32 GMT

Thank you for the update Ross.

I do maintain 16+1 SDP format and all irrelevant bits are set to 0. I get Report3 back from the device and I do not get Report4 which according to the Vybrid manual is the sign that jump was successful.

It occured to me that I might be using illegal part of memory. My program is stored starting from 0x3f000000 address which is mapped to OCRAM-SysRAM0, it might be the case that it's used by boot rom so I overwrite its data structures. What are legal address ranges to store program binary loaded via Serial Downloader?

Many thanks,
Pawel

Your image must be formatted with IVT, DCD, etc. It is not a straight code image/routine address. The same code executes for engineering/production so where the HAB is validating an image all the same structure/code must be present. You can use one of the bootable MQX Cortex-A5 projects for instance.
