Greetings,
i am trying to interface M25P80 slave with stm32f103 master the main thing is after writing write enable instruction It won't set WEL bit in RDSR(0x05) !!! i am running SPI1 in master mode pin configuration for nss,sck,miso,mosi as GPIO_Mode_AF_PP, 50MHZ and HOLD as GPIO_Mode_Out_PP, 50MHZ
SPI configuration as 8bit data mode, msbfirst, CPOL =1, CPHA =1
after enable the RCC to GPIO pins and SPI1 making Chip select to low and HOLD to high then
->making chip select to low
->sending write enable(0x06)
->checking for status while(checkstatus(WEL) == Reset);
but after above it won't step to next instruction i think it won't set the WEL bit in status register !!
i observed using oscilloscope that MOSI sends the instruction correctly, and HOLD(low active) and W(write protect low active) is also high
but where might be the bug???
Thanks and Regards.
