Hi, I'm using the omap3530 spi interface as a slave to receive data from a cpld configured as a master.
The master sends 8-bit words to slave, the slave receives. However, during my test, there's a bizarre problem: if i try to receive 8 words in slave, there's simply no response from the slave no matter how many words i send from the master, but if i try to receive less than 8 words(eg. 1-7), the communication works perfectly.
As a result, I'd like to ask if there's a limit for a SPI slave to receive for a single time, and if that's the case, i'm wondering how can I push the limit because i need to receive at least 128 words a time.
Thank you very much.
