Hi Luca, I'm trying to calibrate my device as suggested, following the guide found at: http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_Calibration_Proccess_NLCP In particular I'm trying to replicate the example at the end of the document and at step 3 of the example I'm obtaining: root@(none):~/ti-utils# ./calibrator plt calibrate wl1271: power up chip_id read from memory: 04030111 wl1271_fetch_firmware - fetching firmware wl1271-fw.bin wl1271_fetch_nvs - fetching firmware wl1271-nvs.bin enable_interrupts_wl1271 wl1271: firmware booted in PLT mode (Rev 6.1.0.50.350) Fail to calibratwl1271: power down e ith radio statdisable_interrupts_wl1271 us (-80) root@(none):~/ti-utils# Any idea about why my calibration process is failing ? I was able to complete the first steps creating the nvs from ini files But I'm failing in "calibrator plt calibrate".

Yes, I guess calibration is the most likely cause now. > In our CMD0 we have > > bit 13 = 1 IB interrupt is active high > > bit 14 = 1 IB interrupt is open drain > > Do you think is right according do RISING_EDGE interrupt ? I think this is okay. I don't think the problem is the interrupt now. You should try to calibrate your device and generate a proper NVS file. -- Luca. ��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
