stm32mp1 host: util_spi_stress -t 4 failed #160

Hi,

trying to run lora_gateway on stm32mp1 host, all tests are passed except write/read burst with BUFF_SIZE >= 16. Read returns array with the different first element, after first element all data equals to data from written array. Tried to change k[x].cs_change, but it did not help.

lgw_spi_wb:332: BURST WRITE: to trans 2 # chunk 2 # transferred 2 
Note: SPI burst write success

lgw_spi_rb:412: BURST READ: to trans 16 # chunk 16 # transferred 16 
Note: SPI burst read success
error during the buffer comparison
