LP87745-Q1: SPI write 無法寫入 LP87745-Q1

Part Number: LP87745-Q1
Other Parts Discussed in Thread: AWR2944EVM,

您好:

我使用mmwave_mcuplus_sdk_04_04_01_02之 MIBSPI driver控制 AWR2944EVM上之LP87745-Q1 register ,

我可成功的讀取 LP87745-Q1的 register value, CRC check 也Ok.但在寫入 LP87745-Q1 register時卻怎麼也寫不進去。

我根據datasheet 對 REG(0xA) 寫0x9B. 但去讀 REG(0xA)時,值都為 1( lock status).請問有什麼狀態會造成,SPI write

無法寫入的情形?該如何處裡?
