how much i set Number of MB when i use can-fd?

[rlaxortn]

i am using s32ds rtd 4.0.0 and s32k344

i already completed to develope for using can-fd, when i set payload size is 8. 

but can-fd is supported payload is 64 bytes. 

so when i set payload is 64 bytes, and number of MB is 31, i got a error. 

if i use payload is 64 bytes by can-fd, how much i set number of MB?

thanks.

Hi,

in case of 64byte payload setting, the RAM block can hold up to 7 MBs.

As FlexCAN 1 has 2 RAM blocks (64MBs @8byte payload) then Number of MB configured can be 14 max.
