Hello ``` I testing now a Q2687 Ex ID : ES1 width the latest FW B74J00gg.Q26EX001 . I test a working software (working on q2687 finely ) but i have a little problem width the parallel bus on the Q2687Ex . (I test the compiled software on a q2687 standard width 6.20 and i download that file to the extreme ) The Software are runing but the pbus init send back a error code (on the Q2687 is working fine ) -2 these mean a parameter error . Here the code : adl_busParallelSettings_t local_setting = { ADL_BUS_PARALLEL_WIDTH_16_BITS, //width ADL_BUS_PARALLEL_MODE_ASYNC_INTEL, //mode {0x00 , 0x00}, // NC , NC {2, 3, 1, 3, 0, 0, 0, 0}, //read timing {2, 3, 1, 3, 0, 0, 0, 0} {2, 3, 1, 3, 0, 0, 0, 0}, //write timing {2, 3, 1, 3, 0, 0, 0, 0} { ADL_BUS_PARA_CS_TYPE_CS, // CS 3, { 0x00,0x00 } }, { 0, 0 }, //PageCfg { 0, 0, 0, 0, 0 }, //Synch Cfg 0x03FFFFFF //Address pin }; local_handle = adl_busSubscribe ( ADL_BUS_PARALLEL , 1 , ( adl_busSettings_u * ) &local_setting ); What is the difference on the extreme ? Thanks ... ``` ---

A program written for 6.2 firmware needs to be rewritten for 7.4 firmware, The 7.x firmwares are not backwards compatible to the 6.x firmwares. ---

No no the program writen on R73 . R74 compiler core is 6.30 , R73 is 6.20. The version in Q2687Ex is 6.20 . Correctly runing on standard Q2687 width R73 or R74 . But error code dropped on 2687Ex . ---

After oasis the openat package number and the fw number in wopen=2 not same . R74 = 6.30 R73 = 6.20 R72a = 6.12 R72 = 6.11 etc … ---

hmm ``` I get a warning from the compiler in these section : ``` adl\_busParallelSettings\_t local\_setting = { ADL\_BUS\_PARALLEL\_WIDTH\_16\_BITS, //width ADL\_BUS\_PARALLEL\_MODE\_ASYNC\_INTEL, //mode {0x00 , 0x00}, // NC , NC {2, 3, 1, 3, 0, 0, 0, 0}, //read timing {2, 3, 1, 3, 0, 0, 0, 0} !!! Warn on these line !!! {2, 3, 1, 3, 0, 0, 0, 0}, //write timing {2, 3, 1, 3, 0, 0, 0, 0} { ADL\_BUS\_PARA\_CS\_TYPE\_CS, // CS 3, { 0x00,0x00 } }, { 0, 0 }, //PageCfg { 0, 0, 0, 0, 0 }, //Synch Cfg 0x01FFFFFF //Address pin }; ``` On the marked line i get a "extra bracket in these line" waning . But i dont where these extra bracket . May these is the problem ( -2 error ) ? But why work on 2687h ? ``` Mzs ---

I get information from these , these is a Firmware fault . Maybe corrected in the 7.4a package , in the first Q26EX pack . ---

Yess now WONRKING Finaly ``` The problem is the follow : On Q26EX differs from Q2687 in CS types but not in the documents :slight_smile: Q2687 = Q26EX CS2 = CS4 CS3 = CS5 ```
