Mach XO2 256HC programming failing

« on: February 23, 2019, 06:14:51 pm » Made a test breakout board for LCMXO2-256HC-4SG32 (QFN 32)Cannot program it, the programmer is failing with the following:Loading logical preference informationFinish loading logical preference fileLoading logical design informationFinish loading logical design informationStarting: "pgr_program run"INFO - Check configuration setup: Start.INFO - JTAG Chain Verification. No Errors.INFO - Check configuration setup: Successful.INFO - Device1 LCMXO2-256HC: FLASH Erase,Program,VerifyERROR - function CHECK_SECURITY_PROTECT_KEYERROR - Process Operation Failed.INFO - Elapsed time: 00 min : 00 secERROR - Operation: unsuccessful.ERROR: pgr_program failed.ERROR - Programming failed.I've added a 4.7K pulldown to TCK, also connected TDO, TDI and TMS.Is it just bad soldering or bad chip?I'm new to soldering QFN packages. Used drag soldering with a gel flux (Flux Plus NC)First soldered the exposed pad with solder paste and hot air, then applied flux and drag soldered the pads.Kind of difficult to check electical connections to the pads with this type of package There seems to be no shorts from my continuity testing.Any other diagnostics in Diamond to tell if the device is properly connected except trying to run the programming?

There is a OTP bit that permanently blocks reading or programming. Logged The following users thanked this post: Axk

Try a programmer command that's something like "verify the feature bits". Logged The following users thanked this post: Axk

« Reply #6 on: February 24, 2019, 05:34:36 pm » Trying to find the programmer software that supports reading these bits.The diamond progammer doesn't appear to have this option.A KB article http://www.latticesemi.com/en/Support/AnswerDatabase/4/1/0/4104 refers to using the ispVM programmer, but I cannot find a version that supports MachXO2 devices.

« Reply #7 on: February 24, 2019, 09:32:59 pm » An older version of diamond programmer software kind of works, it doesn't give any errors and the part reacts to the programming.But it doesn't see the clock input for some reason.The same basic design works fine in an RTL simulation. « Last Edit: February 25, 2019, 09:30:10 am by Axk » Logged

The bug could be something that becomes active when the part is programmed - OK at the start when all the FPGA outputs are inactive and floating weakly high, bad when the outputs go active. Logged

« Reply #11 on: March 16, 2019, 06:27:59 am » Could you please post the schematic and some board layout pictures, maybe there is something wrong with the schematic itself. These chips have several VCC PINS did you connect them all ? Logged

Which programmer are you using?

A USB programmer from ebay, labeled and detected by the Diamond programmer as HW-USBN-2AI've tried adding a 33pf from TCK to ground (on an external breadboard) and it is still failing with the same "ERROR - function CHECK_SECURITY_PROTECT_KEY"This same programmer works fine with LCMXO2-1200HC-TG144C.Maybe I should try a different programmer... « Last Edit: March 17, 2019, 02:10:15 pm by Axk » Logged

The programmer that you have is usually realiable.You need to give us more of the schematic, a snip isn't enough. Logged The following users thanked this post: Axk

Re: Mach XO2 256HC programming failing

« Reply #16 on: March 17, 2019, 08:49:24 pm » D'oh!It works now.2 aspects:1. The programming doesn't work with the latest version of the diamond programmer (3.10.3.144), it gives this weird "function CHECK_SECURITY_PROTECT_KEY" error (I guess this is because the cable needs a firmware update, the only info I've found on Security Protect Key is that it's a feature of the Lattice XO3 family)2. An older version of the Diamond programmer (3.8.0.115.3) does work, it was my bad soldering I soldered the JTAG "pins" correctly, but the "pins" I was trying to blink the test LEDs with were not soldered properly (or maybe the power "pin" for the bank)Takeaway - when hand-soldering QFN packages make sure to apply as much solder as possible and still doesn't short the "pins" (also make the pads longer so that you have room for the soldering iron to apply solder).I didn't use the capacitor between TCK and ground (but will provision for it in my future boards just in case).The JTAG pins connected in my case are: TDI, TDO, TCK (with a 4.7K pulldown) and TMS « Last Edit: March 17, 2019, 08:58:04 pm by Axk » Logged

This is specific to the LAttice USB programmer, which may have been fixed as it's a pretty old unit, so I wouldn't bother, as it may cause issues with other programmers - put it on the programmer instead if it's an issue Logged Youtube channel:Taking wierd stuff apart.

Though it may have been fixed via updates, I haven't had luck with Diamond 3.10. I'm still on 3.9, plus 2.0 for some stuff that got removed in the 3.x releases. Logged
