Hello all. I am working on Sm1000 hardware circuit design. My first step is to design complete circuit of "SM1000 Version F" available on GitHub. I completed this part, I used almost same components that mention in the schematic but few of them are alternate. My second step is to test the power circuit of Sm1000, I completed this part too and verify+5V and +3.3V power circuit. My circuit takes three different veroboard to complete and I aslo connected VDD, AVdd and grounds of all veroboard together and verify (short circuit or not). I connect all the components exactly as on the schematic-F. In third step I am using STM32F407 discovery board and upload the"dfuse file" available on the github and follow the procedure same as mentioned on github. During upload I verify the product ID and vendor code exactly as mentioned on GitHub. In forth step, I start connecting SM1000-F with STM32F407 as per the schematic design F.
During these four steps I faced some problems and looking for a kind response from all experts. 1. When I upload dfuse file to stm32f407 discovery board, it shows upload successful "file size of 293KB but when I opened the properties of stm32 memory shows only 8KB or sometime 20 KB of data in it. 2. Stm32F407 have 100 pins on two sides, mentioned as P1 and P2, both P1 and P2 has 50, 50 pins... When I start connecting schematic F with discovery board of STM 32F407, I easily connect "PE1 with PE1" (nets connection) as mentioned.. but when I move towards power circuit of STM32F407 than I am confused, as on STM32F407 schematic F power circuit labeled as "U1B" grounds and VDD pins are not same as on the discovery board of STM32F407. Like Vref+,VBat, Bad, vdd2 etc. 3. When I turn on the circuit design on vero board, all the connections are okay, I measured and verify 5V in power circuit. But"pwr_led" available on schematic F (led-0) not ON and when i pressed PTT than"LED PTT" also not working but when i measured voltage with multimeter on these 2 LEDs than both LEDs have 3.3V available. I really appreciate your answers. Thanks in advance. Regards: Usman
