Re: 128 Kb CPU hangs up when 128Mhz overclocking is applied STM32103

if you like mozzi https://github.com/sensorium/Mozzi i'd suggest to make an attempt of a port say to stm32f405 or stm32f407 (stm32f407 mainly has more IO hardware but tend to have less sram and flash vs stm32f405, stm32f405 rg has 1m flash and 512k sram) adafruit, micropython, olimex has boards wit...

Re: 128 Kb CPU hangs up when 128Mhz overclocking is applied STM32103

It is asking too much for operating conditions not covered by the specifications. One may purchase a bunch of 128k and do the screening. A possible bet is to check if the 64k chip is actually a 128k. Almost all 64k bluepills I got have 128k embedded flash. I have seen many hobbyists overclock the c...

Re: 128 Kb CPU hangs up when 128Mhz overclocking is applied STM32103

ok here are some suggestions, Mozzi is apparently adapted to run on 'rogers' (libmaple) core on stm32f103 https://github.com/sensorium/Mozzi however, it isn't adapted for 'new' hardware. e.g. 'steves F4' (which is also in 'rogers') (libmaple) core if you try to run that on the 'official' stm32duino...

Re: 128 Kb CPU hangs up when 128Mhz overclocking is applied STM32103

normally one would escape if system clock is marginally higher than spec e.g. stm32f411 has a spec for 100 mhz max, but if you need usb it is 96 mhz max stm32f401 has a spec fo 84mhz, i tend to be able to do that stretch for 96mhz, any thing more it breaks. and for what is worth this is kind of i g...

Re: 128 Kb CPU hangs up when 128Mhz overclocking is applied STM32103

NO ERRORS for both cases the compiler would have no way of knowing if you over-clocked the chip. I tried this way back but I remember those chips doing no problem in the 90 - 108Mhz territory. 128Mhz might just be too much for a 72Mhz-rated device. In comparison, PIC32MX (50Mhz rated) could do 60Mh...

128 Kb CPU hangs up when 128Mhz overclocking is applied STM32103

In arduino 1.8.3, when i select the 128 Mhz overclocking option CPU hangs up for 128 Kb memory version; the same code runs ok at 72 legacy frequency. In 64 Kb version, at 128 Mhz, everything is ok. Both chips are original STM and the Arduino compiler gives back NO ERRORS for both cases. I cant under...

STM32F103CB STLink V2 OSX stops upload

Hello there! Got a STM32F103CB board. In Arduino IDE 1.8.13 running on WIN7 all goes ok. Tried 2 different STLink V2 chineese clones. Same results. Arduino Log: STM32 ST-LINK CLI v3.3.0.0 STM32 ST-LINK Command Line Interface ST-LINK SN: 48FF6E065188515532321067 ST-LINK Firmware version: V2J37S7 (Nee...
