LPCOpen Keil Freertos project issue

daweiyou — Wed, 24 Jan 2018 13:53:40 GMT

Recently I tried to use LPCopen for LPC11U68 and LPC824, but latest LPCOpen SDK 3.02, the Keil project of freertos_blinky both couldn’t work in default project setting.

The LPC11U68’s project, default optimization level is 3, after change the optimization level from Level3(default) to 0, the project could work;
But the LPC824-MAX, even if change the optimization level, which could not work yet.

Could someone have a look at such issues? Thaks.

The project and LPCOpen SDK version is like as below:

lpcopen_3_02_keil_iar_nxp_lpcxpresso_824

lpcopen_3_02_keil_iar_lpcxpresso_11u68

keil\freertos_blinky

Hi Dawei,

I'd like to update you on the issues.

The freertos issue on lpc824 is due to the wrong definition of heap size in keil_startup_lpc11u6x.s. To fix it, need to modify the definition like:

Heap_Size EQU 0x00000600

Regarding the issue on lpc11u68, I will check it soon...

Hi Dawei,

Concerning the issue on lpc11u68, it's due to a wrong configuration of the include path related to FreeRTOS.

To fix it, need to change
