Hello,I want to program the device using SWIM interface, The host is FPGA, but the device can't response successfully.When I reset the SWIM, the return value is wrong, and write SWIM_CSR could not successfully.I attach the wave form picture, please h...

Hi,I want to program STM8S001J3M with SWIM interface, and the device doesn't have NRST pin, I see in the datasheet there is :Only the “connect on-the-fly�? method can be used to program the device through the SWIM interface. The “connect under-reset�...

Hello,I see in the datasheet:The “connect on-the-fly�? mode can be used while the device is executing code, but if there is a device reset (by software reset) during the SWIM connection, this connection is aborted and it must be performed again from...

Hello Cristian,Thanks for your reply.I just do 4 step,write SWIM entry sequence, Does the SWIM entry sequence of this device is 8 bits: 4 pulses at 1ms, followed by 4 pulses at 0,5ms? Does it need change?send SRST sequence to reset system.write SW...

Hi Cristian,Thank you very much, The explanation is very clear.I would like to ask one more question, does the STVP support to program STM8S001J3M? I use the ST link to program the device, but it always connect failed.Thanks!
