New PIC32MZ DA

[Howardlong]

...with the internal RAM?

http://www.microchip.com/Developmenttools/ProductDetails.aspx?PartNO=DM320010    $130  and lots in stock.

Ordered two yesterday, and they just arrived on my desk!

Please post about it!

There's not much to say if I am to compare it to the PIC32MZ EF SK boards which it's similar too in size and layout. They've moved from USB mini to USB micro for the serial emulation and Debug connection (USB mini has been used for some years for PICKit-on-board [PKOB]), so you need to make sure you plug in your cables right as there are now _four_ USB micro connectors on the board: Debug, Serial emulation, the DUT's USB OTG, and an external power-only connection.

Like the PIC32MZ EF SK boards, there is a 20x2 pin 0.1" pitch header which affords handy access to one each of the DUT's SPI, I2C and serial ports which match the pinout of the PIC32MZ EF's header. There are also a number of GPIOs on it, but note that the individual GPIOs themselves are completely different between the DA and EF SK boards. While the 20x2 header is populated on the EF SKs (at least on the half dozen or so I have), it isn't on the two DA SKs I have.

The 0.05" 6x1 ICD header isn't populated on the DA board but it is on the EF board. Like the EF board there's a populated miniature jumper to switch between PKOB and external debugger.

The DA board also has a populated micro-SD card socket and lands for an unpopulated JTAG connector.

Like many other Microchip SKs with DUTs that support OTG/Host USB, there's a standard USB 2.0 Type A receptacle on the DA board.

Before operating, I updated to the current latest software suite:

o MPLAB X IDE 3.61
o MPLAB XC 1.43
o Harmony 2.03b - I used the MHC from this package as it's currently the most up-to-date

Certainly for full support of the DA devices you need XC 1.43 (there was beta support for earlier releases). Harmony 2.03b appears to be required for BSP support for the DM320010 with integrated DDR.

I ran two of the demos (write_read_ddr2 and dma_led_pattern) and they ran fine first time. Although I do have the MEB2, beyond those two demos I've not yet tried. There are about a dozen application examples supporting the DM320010 including SD card, graphics and LAN. There are a couple of additional graphics app demos supporting the DM320008 (with external DDR2) but I don't believe there's a reason why the demos couldn't also be made to work with the DM320010 once you've mastered Harmony to a reasonable enough level (good luck with that).

Not much more to say I'm afraid.

Rumour has it that there will be a SAMA52  with 128Mbit, 512MBit or 1GBit DDR2 in package sizes from 196 to 289 contacts,  and it will be released in July.
Microchip already have a working port of Linux for this.

This might be a better choice for running linux on than the DA..  but we'll have to see how the pricing comes out.

I tried the MEB2 briefly yesterday with a couple of the gfx demos. Unfortunately, the display on mine has gained a crack and it looks like the touch screen no longer works. However the display itself still works. The demos worked although the splash screen demo I couldn't get to compile properly with the internal DDR MEB2 legacy build, there were some undefined references to DDR fields. It did compile with other builds.

I am definitely going to get my hands on one of those. THe AT91SAM9260 is old and V3s lacked mainline support.

Packaging listed:   11x11 BGA196, BGA289 (in 0.8pitch) package and also an ultra-small package option BGA256 (8x8mm in 0.4 pitch)
Always a fly in the ointment for me, I would need a QFP.

I have been looking at the AllWinner V3 , not to run Linux but to run freeRtos instead. The price and availability look to be good - for now, but with AllWinner who knows for how long. I don't particularly want to put in the effort of porting freeRtos (sigh).

Allwinner designed their chips to run Linux. If you want FreeRTOS you are likely on your own. And yes their availability track record wasn't that great.
