Hi All, I figured out that the ChannelInfo_t structure was misaligned. The channel plan, ChannelPlan_t, contains an array of ChannelInfo_t (ChannelPlan_t::channels). ChannelInfo_t::preambleBitmap is a 15-byte character array. Channels after ChannelPlan_t::channels[0] fell on un-aligned addresses. I didn't go back and look but I suspect somewhere in the structure declarations there is a 'packed' attributed. This would explain why the compiler didn't pad ChannelInfo_t::preambleBitmap. To keep moving forward, I simply changed (wmxSDK_Nds_Cmn.h): typedef UINT8 wmx_Preambles_t[PREAMBLES_LENGTH], *wmx_pPreambles_t; to typedef UINT8 wmx_Preambles_t[PREAMBLES_SIZE], *wmx_pPreambles_t; and added #define PREAMBLES_SIZE 16 After doing this the scan parameters sent to the device look correct and WiMAX_DB.bin is no longer updated/altered with BW and FFTSize set to -1. ... on to the next problem. I noticed that only half the channel plan is sent to the device. This causes the device to hang in scanning. This may be a topic for another thread. I wanted to post my findings to complete this thread.
