Hi all,
I working on project with LPC1227. My application using many of libraries, previously created on linux.
These libraries were previously compiled and used on LPC1768 based project.
Now I have compiled these libraries for LPC1227.
When I run my test application, application will be stopped and stay dead.
I have debug, where is problem.
Problem occure when start condition with reading value of pointer *crc:
if(*crc == crc_calculated) // Do this, will trigger HardFault_Handler(void) in cr_startup_lpc12xx.c file
{
...
All parts of used code are here:
typedef struct _ANB_SESSION_
{
...
uint8_t rx_buff[40];
...
}
ANB_SESSION;
ANB_SESSION *anb_session;
uint16_t *crc;
crc = (uint16_t *)&(anb_session -> rx_buff[anb_session -> first_byte_datagram_index + sizeof(ANB_DATAGRAM_HEADER) + anb_datagram_header->Len]);
if(*crc == crc_calculated) // Do this, will trigger HardFault_Handler(void) in cr_startup_lpc12xx.c file
{
...
}
Index of rx_buff in assignment is 28 and rx_buff is 40 bytes long.
Address filled in pointer crc is 0x10000329 and pointed value is 32292 decimal.
Local variable crc_calculated has same value (32292). Type of local variable crc_calculated is uint16_t.
When I click with cursor in debugger on variables in condition, displayed values are correct.
After do condition, then will be triggered HardFault_Handler.
I still using LPCxpresso v7.6.2 [Build 326] [2015-02-02] for LPC1227 and before LPC1768.
All libraries are only precompiled from LPC1768 to LPC1227 and used equaly.
Thank you for your help

Hi Milos,
Besides of LPCxpresso v7.6.2 [Build 326] [2015-02-02] IDE, what's the hardware board you are using?
Could you provide the software project?
best regards,
Mike
