在表2:SPI主引导协议，什么时候会收到ACK/NACK ?
-当发送0字节时
或
-当发送LS字节的长度?同样，根据表的最后一行(字节nr.8)，当发送数据的第一个字节时，将接收到code/mode的ACK/NACK，
但这与下一个表不对应。
我感觉所有MISO列的值向下移动了一行。< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / spi”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > spi < / > < / div > < div类= " field-item奇怪" > < a href = " / resource-keywords / booting-spi-master”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >从SPI主启动< / > < / div > < / div > < / div > < div class =”字段field-name-field-device field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >设备:< / div > < divclass="field-items">

I am using CPOL = 0 , CPHA = 0 and a clock of 330 kHz. The CS line is held logic low the whole time without any toggling.

I am using 0 as mode byte ( Byte nr = 6)
I get the Preamble ACK and Length ACK (0x2) at Byte nr. 3 and 6 as expected. But I get a value 0x7F at Byte nr. 8 .

Basically, when I send
spi_TX_buf[10] = {0x70, 0x50, 0, (BLE_CODE_SIZE >> 2) & 0xFF, (BLE_CODE_SIZE >> 10) & 0xFF, BLE_CODE_CRC, 0, 0, 0, 0 }; //Make the first two byte of code as 0 for debug
I get back
spi_RX_buf[] =
[0] (0x00)
[1] (0xDC)
[2] (0xD4)
[3] (0x02)
[4] (0xE5)
[5] (0xC4)
[6] (0x02)
[7] (0xC0)
[8] (0x7F) //This should have been 0x02 or 0x20
[9] (0xFF)

what could be wrong?

Ashwin
