How to verify the Cortex-M0 thumb instructions ? I found one chip( RAM &FLASH is OK) when it run LDR relative instructions,the program is in Hardfault。But others run the same code is OK

Could you help me to solve the problem.Do you have the code to verify the thumb instruction ? If have,the code can check any corner the functions of thumb instructions

Code simulates ok, but doesn't run in chip

Hi. I have this simple code that defines some constants in code: #include <REG922.H> code const unsigned char LEDRegister0[] = {0xff,0xfe,0xfd,0xfb,0xff,0xff,0xff,0xff,0xf7,0xff,0xff,0xbf}; ...

Tasks can't switch to others, always run at OSStartHang. but whitout boot code ,the app can run ok. the core of the chip is cortex-M0

The app is ucos II. OSStartHighRdy LDR R0, =NVIC_SYSPRI14 ; Set the PendSV exception priority LDR R1, =NVIC_PENDSV_PRI STR R1, [R0] ; Not storing entire byte with STRB to avoid error MOVS R0, #0 ;...
