SQI Drivers Availability

Hi,

I am using PIC32MZ2048ECH144/100 Micro-controller for one of our projects. I am using Microchip Harmony + MPLABX IDE + XC32 V1.40 for the development. I want to use SQI Port for interfacing a Serial Flash working on SQI (SST26VF064B or so). If I try to select the SQI driver from Driver Section of Harmony, it gives a warning message saying "****Warning: Driver Implementation is not available. Only pin management functionality is enabled in this release. ****". Also, I do not see the drivers for the above mentioned SST chip (on the similar lines of SD Card or SST25VF064C).

I am trying to develop the SQI drivers for the uC and Flash as well but I am a bit doubtful about the reliability of these.
Please me know the timeline at which SQI drivers will be made available to user.

Awaiting for you reply.

Thanks & Regards,
Pranav

Pranav,
 
The SQI drivers are planned for v1.07/v1.08 of the Harmony release (release schedules are still uncertain).
 
However, the following code examples in latest Harmony release (v1.06) should help you with the task:
Basic flash setup, write and read:
apps/examples/peripheral/sqi/flash_read_dma_mode
apps/examples/peripheral/sqi/flash_read_pio_mode
apps/examples/peripheral/sqi/flash_read_xip_mode
 
SQI to store images and retrieve them onto screen
apps\meb_ii\gfx_photo_frame
 
Feel free to post any specific questions that you might have on the SQI functionality in general.

The examples above only work with the PIC32MZ EC Starter Kit, but do not work with the starter kit I/O expansion board.
 Does anyone know why?
Thank you.

Hi,
 
it's not a promise, i'm using it. But you have to use the 2.02b harmony version.

Hi,
 
I am using MPLABx-IDE V3.65 with Compiler XC32 V1.44 and Harmony V1.11.
I am also facing the issue that driver is not implemented for SQI interface in Harmony 1.11
Please suggest me how to proceed.
1) Whether the latest Harmony supports SQI interface?
2) If i replace the Harmony 1.11 by the latest Harmony, will it help me?
3) do i need to change the IDE& compiler for the latest Harmony?
4) Can i have two harmony versions at my PC?
5)How to use "apps/examples/peripheral/sqi/flash_read_dma_mode" files in harmony project?


Thanks in Advance
Indira

You can have multiple versions of MPLabX installed. Each of those can have only one version of MHC installed.
You can have many different versions of Harmony installed.

Oh, It is a great information. Thanks to NKurzman, for the Response.
 
I have already developed some projects using old harmony.
Now if i use new Harmony, will it have back compatibility?
do i need to switch over from new to old harmony?

Indira

Moving a project from an old version of Harmony to a newer one has challenges.
I have old Posts for V1.04 to V1.11.  Moving from V1.XX graphics it 2.XX may not be possible without major rewriting of code.  I have no idea what they did with V3.XX.
 MHC is neither forward or Backwards compatible in any version.

Thanks to NKurzman, for the valid information.
 
I am planning to install the latest IDE, XC32 with latest Harmony configurator as you suggested.
Let me see whether I get SQI driver implementation in the new harmony configurator.
 
Only doubt is, whether my i3 processor supports the latest IDE. Anyway I update the status in my post here.
 
Thanks & Regards,
Indira
