## NAME

pyocd-tool - ARM Cortex-M programming tool

## DESCRIPTION

**pyocd-tool** is an ARM Cortex-M programming tool

### Summary

pyOCD is an Open Source python based library for programming and debugging ARM Cortex-M microcontrollers using CMSIS-DAP.

Includes support for flashing new binaries, resetting the device, halt, step, resume read/write memory and set/remove breakpoints.

### Support

Firmware files included in the upstream source are NOT included in the Debian package due to a lack of source code. Target files can be downloaded separately from  \<https://github.com/mbedmicro/pyOCD/tree/master/binaries\>

Available targets for use with --target option: lpc824, kinetis, w7500, kv11z7, lpc4088qsb, kv10z7, k20d50m, ncs36510, kl28z, kl25z, k82f25615, k28f15, maxwsnenv, max32600mbed, k22fa12, lpc4088, lpc4330, ke18f16, kl46z, stm32f103rc, kl82z7, lpc54114, kl43z4, kl26z, lpc11xx\_32, lpc800, rtl8195am, kl05z, lpc1768, kw41z4, lpc4088dm, stm32f051, cortex\_m, lpc11u24, kl02z, kw01z4, k64f, k22f, ke15z7, nrf51, nrf52, kl27z4, kw40z4, k66f18
