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

  • We have run the code on an FPGA,the result of R2 is 0x08. But only the one chip is bad, others run the same code is OK。We try to pick pu bad chips which have the same problems, when  test chip in FT. But we don't know  how to check the functions of CM0,Can you give me some methods?
