Build failure when building for LPC11U35_401 with ARMC6 #15

RonEld · 2019-09-08T07:05:17Z

Building the example for LPC11U35_401 with toolchain ARMC6 results in the following build error:

I believe the Undefined symbol _scanf_mbtowc error has been fixed in ARMmbed/mbed-os#10704 and the mbed-os.lib requires updating to latest versoin, once next Mbed OS release is published.
I believe error Undefined symbol us_ticker_irq_handler is because the targets.json doesn't have device US_TICKER for LPC11U35_401 . To resolve this, either add US_TICKER DEVICE in ``targets.jsonor add#if DEVICE_USTICKER` in the targets' us_ticker.c file

Note that same errors happen with ARM toolchain which is mentioned as supported toolchain

To resolve this, either add US_TICKER DEVICE in ``targets.jsonor add#if DEVICE_USTICKER` in the targets' us_ticker.c file

thanks for the report. @RonEld Can you send a patch to Mbed OS fixing this us ticker?

RonEld · 2019-09-09T08:51:48Z

@0xc0170
I don't mind doing it, but I don't have the target to test.
In addition, I don't know what's the best solution for this:

add US_TICKER DEVICE in targets.json
add#if DEVICE_USTICKER` in the targets' us_ticker.c file

1 means the target has us ticker, which I don't know
2 means not using the us ticker, in case there is.

Shouldn't this be done best by the partner?

0xc0170 · 2019-09-09T09:15:30Z

add#if DEVICE_USTICKER` in the targets' us_ticker.c file

This should be OK to do without target testing as long as build is all good for this target. For the 1st, we would need target testing.. However if us ticker was ported and we introduced this new define few months back, I dont see a reason why not add it - is the target usable without us ticker? It's not.

0xc0170 · 2019-09-09T09:15:50Z

cc @toyowata would you be able to test us ticker for this platform?

toyowata · 2019-09-10T08:01:26Z

@0xc0170 @RonEld

I just quick test for this platform. My test branch is here:
https://github.com/toyowata/mbed/tree/test_lpc11u35

I did...

Add USTICKER for the target
Add #if DEVICE_USTICKER macro in the us_ticker.c

I still got link erros, so I changed:

Change default_toolchain from uARM to ARM

Now, I got no link errors. Then, I copied the mbed-os-example-blinky-baremetal binary to the target and got runtime error below:

Note that -t gcc_arm binary doesn't crash and works as expected (LED blinks every 500ms) on the target.

The LPC11U35_401 is Mbed 2 only target. There should be done proper porting/testing for Mbed OS 5 even baremetal profile?

baremetal should equal to mbed 2 (at least if we are concerned here about ARM toolchain). It should work.

Thanks for testing,the target is broken and no longer builds :/

0xc0170 · 2019-09-10T08:15:17Z

Not even regular test builds? This might move to Mbed OS and should be fixed.

RonEld · 2019-09-10T13:59:21Z

@toyowata Thanks for testing.
Perhaps the platform doesn't support usticker, and this is why USTICKER doesn't exist in targets.json?
In this case, I think we should only keep the #if DEVICE_USTICKER , which will disable usticker, pass link, but I am not sure on runtime though

@RonEld

I removed the USTICKER feature from the target and it doesn't crash in runtime (ARMC6 build). LED blinks as expected timing and no crash report. My working branch is here: https://github.com/toyowata/mbed/tree/test_lpc11u35

@0xc0170

Not even regular test builds? This might move to Mbed OS and should be fixed.

By adding "5" in the release_versions enables greentea test build, but I got link errors because the target doesn't have enough RAM for all test cases (maybe, linker script files should be updated for the target).
By adding "requires": ["bare-metal"] in the mbed_app.json for test build with above, I got compile errors (not fond headers under the greentea-client).

@toyowata How shall we fix this issue? using your test branch and integrate it via PR to Mbed OS?
