Forum Post: tx_byte_release return TX_CALLER_ERROR

Hi all, I have created a memory byte pool and allocate the memory using tx_byte_allocate in one function. Then i pass the  memory_ptr which is pointer to a destination memory pointer in another function where i call the tx_byte_release api to free the memory pointer, it returns TX_CALLER_ERROR (0x13) Invalid caller of this service. What could possibly go wrong ? Thanks & Regards
