Posted on October 21, 2016 at 01:09HI All,
If I enable usage faults in my F7Discovery project (F769) - I get usage fault in the HAL - specifically in stm32f7xx_hal_dsi.c line ♯ 1281
hdsi->Instance->GPDR=((uint32_t)(*(ParametersTable + uicounter)) | \
((uint32_t)(*(ParametersTable + uicounter+1)) << 8) | \
((uint32_t)(*(ParametersTable + uicounter+2)) << 16) | \
((uint32_t)(*(ParametersTable + uicounter+3)) << 24));
My debug output from the hard fault handler is as follows:
Unaligned access UsageFault<\n>
r0 = 0x0800d541<\n>
r1 = 0x00000000<\n>
r2 = 0x00000039<\n>
r3 = 0x0000000e<\n>
r12 = 0x00000006<\n>
lr = 0x08001cd1<\n>
pc = 0x08001cf0<\n>
psr = 0x01000000<\n>
I would like to enable this for my project but this wont be possible if the libraries are faulting . The code is standard cube code provided by ST.
Any ideas on if this can be fixed ?
Thanks
