* FuriHal: enable HSI in stop mode only if we use STOP0, proper SMPS selected clock assert * Furi: fix double crash caused by bkpt use outside of debug session * Libs: update ERC and MGG contrast * Fix various crashes with LIB_DEBUG=1 * BadUsb: size_t where it should be and proper printf types * Various fixes and make PVS happy * FuriHal: proper CCID status and make PVS happy * boot: update mode: graceful handling of corrupted stage file --------- Co-authored-by: hedger <hedger@nanode.su>
